These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

MAXNANOPWRBD# EV Block DiagramQuick StartThe kit comes preprogrammed with multimeter example firmware. Simply apply power to the board with a 1.5V button cell battery or with an external 1.5V voltage source. SW1 can be used to cycle through the three operational modes: voltage measurement, current measurement, and frequency measurement.Voltage and frequency measurement is relative to the V and COM terminals. Current measurement uses the A and COM terminals.Detailed DescriptionThe MAXNANOPWRBD kit implements a simple bat-tery-powered multimeter to demonstrate several low power Maxim analog and digital technologies. Application functionality is provided by firmware that runs on the MAX32660 Arm Cortex-M4 processor with FPU. The analog front-end is implemented with nanopower com-parators and operational amplifiers that present measure-ment signals to the MAX11615 12-bit ADC. The ADC is connected to the MCU through an I 2C bus.The 128x128 pixel LCD is connected to the MCU through a SPI bus and two buttons are provided to complete the multimeter user interface.The example firmware provided with the kit enables voltage, current, and frequency measurements through the V, A, and COM terminals. Limit voltage measure-ments to ±10V and current measurements to ±100mA. Kit design does not provide protection and safety circuitry required by commercial multimeter designs. Therefore,the kit should not be connected to high-voltage sources. Exceeding the specified input ranges will damage the PCB and the components.The kit can be powered by a single LR44, or similar, 1.5V button cell. The board can optionally be powered externally by a benchtop supply through J2. Maximum input voltage applied to J2 should be limited to 1.5V. SW4 specifies between external power (EXT) and battery power (BAT).The kit features two connectors for external interfacing. J7 provides a JTAG SWD interface that can be used with the included MAX32635PICO debugger module to program and debug the MAX32660 Arm Cortex M4 processor with FPU. J1 provides access to the I 2C bus to interface with the MCU and the ADC. This interface is compatible with Sparkfun’s QWIIC system.Power conversion is provided by the MAX17222, which converts the 1.5V nominal battery voltage to 3.3V for use by the rest of the board.FirmwareA source code package for the kit can be obtained from Maxim website. Simply use the search tool on Maxim’s website and search for “MAXNANOPWRBD”. The pack-age is found on the Design Resources tab.Information about the source code and how to build, program, and debug it can be found in the source code package.#Denotes RoHS compliance.PARTTYPE MAXNANOPWRBD#Evaluation KitOrdering InformationEvaluates: MAX32660, MAX11615,MAX40007, MAX9119,MAX9634, MAX17222 MAXNANOPWRBD# Evaluation KitREFDES QTY MANUFACTURER PART NUMBER DESCRIPTIONBT11KEYSTONE2996BATTERY HOLDER; SMT; 11.6MM BUTTON CELL RETAINER; 0.25MM PHOSPHOR BRONZE;TIN NICKEL PLATEDC1, C32TDK C1608X5R1A106K080AC CAPACITOR; SMT (0603); CERAMIC CHIP; 10µF; 10V; TOL = 10%;TG = -55°C TO +85°C; TC = X5RC2, C10, C123MURATA; TDK;TAIYO YUDEN; TDKGRM155R71E104KE14;C1005X7R1E104K050BB;TMK105B7104KVH;CGJ2B3X7R1E104K050BBCAPACITOR; SMT (0402); CERAMIC CHIP; 0.1µF;25V; TOL = 10%;TG = -55°C TO +125°C; TC = X7RC4–C7, C11, C148KEMET; YAGEOC0402C105K8PAC;CC0402KRX5R6BB105CAPACITOR; SMT (0402); CERAMIC CHIP; 1µF;10V; TOL = 10%; TG = -55°C TO +85°C; TC = X5RJ11JSTMANUFACTURINGSM04B-SRSS-TB(LF)(SN)CONNECTOR; MALE; SMT; DISCONNECTABLECRIMP STYLE; RIGHT ANGLE; 4PINSJ21PHOENIX CONTACT1725656CONNECTOR; FEMALE; THROUGH HOLE; PCB TERMINAL BLOCK; RIGHT ANGLE; 2PINSJ31MOLEX51441-1093CONNECTOR; FEMALE; SMT; 0.5MM FPC CONNECTOR; RIGHT ANGLE; 10PINSJ71SAMTEC FTSH-105-01-L-DV-K CONNECTOR; MALE; SMT; 0.05 (1.27MM) SMT MICRO HEADER; STRAIGHT; 10PINSL11WURTHELECTRONICS INC.74479276222INDUCTOR; SMT (0806); MOLDED CHIP; 2.2µH;30%; 1.40AMH1–MH44KEYSTONE9032ROUND-THRU HOLE SPACER; NO THREAD; M3.5; 5/8IN; NYLONMOD11SHARP LS013B7DH03LCD MODULE;30.3MM X 26.6MM X 0.851MM; SMT;R1, R4, R123VISHAY DALE;YAGEO PHICOMPCRCW040210K0FK;RC0402FR-0710KLRESISTOR; 0402; 10K; 1%; 100PPM; 0.0625W;THICK FILMR2, R32VENKEL LTD.;PANASONICCR0402-16W-3091FT;ERJ-2RKF309RESISTOR; 0402; 3.09KΩ; 1%; 100PPM;0.063W; THICK FILMR71VISHAY;PANASONICCRCW060380K6FK;ERJ-3EKF8062RESISTOR; 0603; 80.6KΩ; 1%; 100PPM;0.10W; METAL FILMR91KOA SPEER SR732BTTDR390F RES; SMT (1206); 0.390; 1%; ±100PPM/°C; 0.33W R101PANASONIC ERJ-3EKF1133RES; SMT (0603); 113K; 1%; ±100PPM/°C; 0.1W MAXNANOPWRBD# EV Bill of MaterialsEvaluates: MAX32660, MAX11615,MAX40007, MAX9119,MAX9634, MAX17222 MAXNANOPWRBD# Evaluation KitREFDES QTY MANUFACTURER PART NUMBER DESCRIPTIONR111PANASONIC ERJ-2RKF1004RESISTOR; 0402; 1MΩ;1%; 100PPM; 0.10W; THICK FILMR131STACKPOLEELECTRONICS INCHMC0402JT33M0RESISTOR; 0402; 33MΩ; 5%; 400PPM; 0.063W;THICK FILMSW1–SW33C&K COMPONENTS KSR231GLFS SWITCH; SPST; SMT; 32V; 0.05A; KSR SERIES; SUBMINIATURE TACT SWITCH; RCOIL = 0.1Ω; RINSULATION = 10GΩ; C&K COMPONENTSSW41ALPS SSSS211900SWITCH; SP3T; THROUGH HOLE; 6V; 0.3AU11MAXIM MAX32660GTP+IC; UCON; ULTRA-LOW POWERARM CORTEX-M4 WITH FPU-BASED MICROCONTROLLER FOR WEARABLE AND IOT SENSORS; TQFN20-EPU31MAXIM MAX11615EWE+IC; ADC; LOW-POWER; 8-CHANNEL; I2C; 12-BIT ADC; WLP16U41MAXIM MAX40007AUT+IC; OPAMP; NANOPOWER OP AMP; GAIN = 1; SOT23-6U61MAXIM MAX9119EXK+IC; COMP; NANOPOWER; BEYOND-THE-RAILS COMPARATORS WITH/WITHOUT REFERENCE; SC70-5U7, U82MAXIM MAX9634TEUK+IC; AMP; PRECISION CURRENT-SENSE AMPLIFIER; SOT23-5U91MAXIM MAX17222ELT+IC; VCON; 0.4V TO 5.5V INPUT; NANOPOWER SYNCHRONOUS; BOOST CONVERTER WITH TRUE SHUTDOWN; UDFN6Y11CITIZEN CM1610H32768DZB CRYSTAL; SMT 1.6MMX1MM; 6PF; 32.7680KHZ; ±20PPMMAXNANOPWRBD# EV Bill of Materials (continued)Evaluates: MAX32660, MAX11615, MAXNANOPWRBD# Evaluation KitMAX40007, MAX9119,MAX9634, MAX17222 MAXNANOPWRBD# EV SchematicEvaluates: MAX32660, MAX11615,MAX40007, MAX9119,MAX9634, MAX17222 MAXNANOPWRBD# Evaluation KitMAXNANOPWRBD# EV PCB Layout—Silk Top MAXNANOPWRBD# EV PCB Layout—Top View MAXNANOPWRBD# EV PCB Layout—Bottom View MAXNANOPWRBD# EV PCB Layout—Silk BottomMAXNANOPWRBD# EV PCB Layout DiagramsMaxim Integrated cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim Integrated product.

BATTERY MANAGEMENT Jul 09, 1998 Switch-Mode Battery Charger Delivers 5AThe fast-charge controller IC3 (Figure 1) normally directs current to the battery via an external pnp transistor. In this circuit, the transistor is replaced with a 5A switching regulator (IC1) that delivers equivalent power with higher efficiency.Figure 1. By controlling the PWM duty cycle of switching regulator IC1, the fast-charge controller (IC3) makes efficient delivery of the battery's charging current.IC1 is a 5A buck switching regulator whose output is configured as a current source. Its internal power switch (an npn transistor) is relatively efficient because V CE(SAT) is small in comparison with the 15V-to-40V inputs. (For applications that require 2A or less, the low-saturation, non-Darlington power switch of a MAX726 offers better efficiency.)R6 senses the battery-charging current and enables IC3 to generate an analog drive signal at DRV. The signal is first attenuated by the op amp to assure stability by reducing gain in the control loop. It then drives IC1's compensation pin (VC), which gives direct access to the internal PWM comparator. IC3 thus controls the charging current via the PWM duty cycle of IC1. The Q1 buffer provides current to the DRV input.Loop stability is also determined by the feedback loop's dominant pole, set by C4 at the CC terminal of IC3. If you increase the value of the battery filter capacitor (C5), you should make a proportional increase in the value of C4. Lower values, however, assure good transient response. If your application produces load transients during the fast-charge cycle, check the worst-case response to a load step. To assure proper termination of the charge, battery voltage should settle within 2msec to 5mV times N (where N is the number of battery cells).

General DescriptionThe MAX6746–MAX6753 low-power microprocessor (µP) supervisory circuits monitor single/dual system supply voltages from 1.575V to 5V and provide maxi-mum adjustability for reset and watchdog functions.These devices assert a reset signal whenever the V CC supply voltage or RESET IN falls below its reset thresh-old or when manual reset is pulled low. The reset output remains asserted for the reset timeout period after V CC and RESET IN rise above the reset threshold. The reset function features immunity to power-supply transients.The MAX6746–MAX6753 have ±2% factory-trimmed reset threshold voltages in approximately 100mV incre-ments from 1.575V to 5.0V and/or adjustable reset threshold voltages using external resistors.The reset and watchdog delays are adjustable with external capacitors. The MAX6746–MAX6751 contain a watchdog select input that extends the watchdog time-out period by 128x. The MAX6752/MAX6753 contain a window watchdog timer that looks for activity outside an expected window of operation.The MAX6746–MAX6753 are available with a push-pull or open-drain active-low RESET output. The MAX6746–MAX6753 are available in an 8-pin SOT23 package and are fully specified over the automotive temperature range (-40°C to +125°C).ApplicationsFeatureso Factory-Set Reset Threshold Options from 1.575V to 5V in ~100mV Increments o Adjustable Reset Threshold Options o Single/Dual Voltage Monitoring o Capacitor-Adjustable Reset Timeout o Capacitor-Adjustable Watchdog Timeout o Min/Max (Windowed) Watchdog Option o Manual Reset Input Optiono Guaranteed RESET Valid for V CC ≥1V o 3.7µA Supply Currento Push-Pull or Open-Drain RESET Output Options o Power-Supply Transient Immunity o Small 8-Pin SOT23 PackagesMAX6746–MAX6753µP Reset Circuits with Capacitor-AdjustableReset/Watchdog Timeout Delay________________________________________________________________Maxim Integrated Products1Pin Configurations19-2530; Rev 1; 1/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Note:“_ _”represents the two number suffix needed when ordering the reset threshold voltage value for theMAX6746/MAX6747 and MAX6750–MAX6753.

The reset output remains asserted for the reset timeout period after V CC and RESET IN rise above its respective reset threshold. A watchdog timer triggers a reset pulse whenever a watchdog fault occurs.The reset and watchdog delays are adjustable with external capacitors. The MAX6746–MAX6751 contain a watchdog select input that extends the watchdog time-out period to 128x.The MAX6752 and MAX6753 have a sophisticated watchdog timer that detects when the processor is run-ning outside an expected window of operation. The watchdog signals a fault when the input pulses arrive too early (faster that the selected t WD1timeout period) or too late (slower than the selected t WD2timeout period) (see Figure 1).Reset OutputThe reset output is typically connected to the reset input of a µP. A µP ’s reset input starts or restarts the µP in a known state. The MAX6746–MAX6753 µP supervisory circuits provide the reset logic to prevent code-execu-tion errors during power-up, power-down, and brownout conditions (see the Typical Operating Circuit ).RESET changes from high to low whenever the moni-tored voltage, RESET IN and/or V CC drop below the reset threshold voltages. Once V RESET IN and/or V CC exceeds its respective reset threshold voltage(s),RESET remains low for the reset timeout period, then goes high.RESET is guaranteed to be in the correct logic state for V CC greater than 1V. F or applications requiring valid reset logic when V CC is less than 1V, see the section Ensuring a Valid RESET Output Down to V CC = 0V.RESET IN ThresholdThe MAX6748–MAX6751 monitor the voltage on RESET IN using an adjustable reset threshold (V RESET IN ) set with an external resistor voltage-divider (F igure 2). Use the following formula to calculate the externally monitored voltage (V MON_TH ):V MON_TH = V RESET IN x (R1 + R2) / R2MAX6746–MAX6753µP Reset Circuits with Capacitor-AdjustableReset/Watchdog Timeout Delay_______________________________________________________________________________________7Figure 1. MAX6752/MAX6753 Detailed Watchdog Input Timing RelationshipFigure 2. Calculating the Monitored Threshold Voltage (V MON_TH )M A X 6746–M A X 6753where V MON_TH is the desired reset threshold voltage and V TH is the reset input threshold (1.235V). Resistors R1 and R2 can have very high values to minimize cur-rent consumption due to low leakage currents. Set R2to some conveniently high value (500k Ω, for example)and calculate R1 based on the desired reset threshold voltage, using the following formula:R1 = R2 x (V MON_TH /V RESET IN - 1) (Ω)The MAX6748 and MAX6749 do not monitor V CC sup-ply voltage, therefore, V CC must be greater than 1.5V toguarantee RESET IN threshold accuracy and timing performance. The MAX6748 and MAX6749 can be con-figured to monitor V CC voltage by connecting V CC to V MON_TH.Dual-Voltage Monitoring(MAX6750/MAX6751)The MAX6750 and MAX6751 contain both factory-trimmed threshold voltages and an adjustable reset threshold input, allowing the monitoring of two voltages,V CC and V MON_TH (see Figure 2). RESET is asserted when either of the voltages falls below it respective threshold voltages.Manual Reset (MAX6746/MAX6747)Many µP-based products require manual reset capabil-ity, to allow an operator or external logic circuitry to initi-ate a reset. The manual reset input (MR ) can connect directly to a switch without an external pullup resistor or debouncing network. MR is internally pulled up to V CC and, therefore, can be left unconnected if unused.MR is designed to reject fast, falling transients (typically 100ns pulses) and it must be held low for a minimum of 1µs to assert the reset output. A 0.1µF capacitor from MR to ground provides additional noise immunity. After MR transitions from low to high, reset remains asserted for the duration of the reset timeout period.A manual reset option can easily be implemented with the MAX6748–MAX6751 by connecting a normally open momentary switch in parallel with R2 (F igure 3).When the switch is closed, the voltage on RESET IN goes to zero, initiating a reset. Similar to the MAX6746/MAX6747 manual reset, reset remains asserted while the voltage at RESET IN is zero and for the reset time-out period after the switch is opened.µP Reset Circuits with Capacitor-Adjustable Reset/Watchdog Timeout Delay 8_______________________________________________________________________________________Figure 4a. Watchdog Timing Diagram, WDS = GNDFigure 3. Adding an External Manual Reset Function to the MAX6748–MAX6751Watchdog TimerMAX6746–MAX6751The watchdog ’s circuit monitors the µP ’s activity. It the µP does not toggle the watchdog input (WDI) within t WD (user-selected), RESET asserts for the reset time-out period. The internal watchdog timer is cleared by any event that asserts RESET , by a falling transition at WDI (which can detect pulses as short as 300ns) or by a transition at WDS. The watchdog timer remains cleared while reset is asserted; as soon as reset is released, the timer starts counting.The MAX6746–MAX6751 feature two modes of watch-dog operation: normal mode and extended mode. In normal mode (Figure 4a), the watchdog timeout period is determined by the value of the capacitor connected between SWT and ground. In extended mode (F igure 4b), the watchdog timeout period is multiplied by 128.F or example, in extended mode, a 0.1µF capacitor gives a watchdog timeout period of 65s (see the Extended-Mode Watchdog Timeout Period vs. C SWT graph in the Typical Operating Characteristics ).MAX6752/MAX6753The MAX6752 and MAX6753 have a windowed watch-dog timer that asserts RESET for the adjusted reset timeout period when the watchdog recognizes a fast watchdog fault (t WDI < t WD1), or a slow watchdog fault (period > t WD2). The reset timeout period is adjusted independently of the watchdog timeout period.The slow watchdog period, t WD2is calculated as follows:t WD2= 0.65 x 109 x C SWTwith t WD2 in seconds and C SWT in Farads.The fast watchdog period, t WD1, is selectable as a ratio from the slow watchdog fault period (t WD2). Select the fast watchdog period by pinstrapping SET0 and SET1,where HIGH is V CC and LOW is GND. Table 1 illus-and 64 window ratio ( t WD2/t WD1).For example, if C SWT is 1500pF, and SET0 and SET1 are low, then t WD2is 975ms (typ) and t WD1is 122ms (typ).RESET asserts if the watchdog input has two falling edges too close to each other (faster than t WD1) (Figure 5a) or falling edges that are too far apart (slower than t WD2) (F igure 5b). Normal watchdog operation is dis-played in (F igure 5c). The internal watchdog timer is cleared when a WDI falling edge is detected within the valid watchdog window or when RESET is deasserted.All WDI inputs are ignored while RESET is asserted.The watchdog timer begins to count after RESET is deasserted. The watchdog timer clears and begins to count after a valid WDI falling logic input. WDI falling transitions within periods shorter than t WD1or longer than t WD2force RESET to assert low for the reset time-out period. WDI falling transitions within the t WD1and t WD2 window do not assert RESET . WDI transitions between t WD1(min) and t WD1(max) or t WD2(min) and t WD2(max) are not guaranteed to assert or deassert the RESET . To guarantee that the window watchdog does not assert the RESET , strobe WDI between t WD1(max)and t WD2(min). The watchdog timer is cleared when RESET is asserted or after a falling transition on WDI or after a state change on SET0 or SET1. Disable the watchdog timer by connecting SET0 high and SET1 low.MAX6746–MAX6753µP Reset Circuits with Capacitor-AdjustableReset/Watchdog Timeout Delay_______________________________________________________________________________________9Figure 4b. Watchdog Timing Diagram, WDS = V CCM A X 6746–M A X 6753Applications InformationSelecting Reset/WatchdogTimeout CapacitorThe reset timeout period is adjustable to accommodate a variety of µP applications. Adjust the reset timeout period (t RP ) by connecting a capacitor (C SRT ) between SRT and ground. Calculate the reset timeout capacitor as folllows:C SRT = t RP / (5.06 x 106),with t RP in seconds and C SRT in Farads.The watchdog timeout period is adjustable to accom-modate a variety of µP applications. With this feature,the watchdog timeout can be optimized for software execution. The programmer can determine how often the watchdog timer should be serviced. Adjust the watchdog timeout period (t WD ) by connecting a specif-ic value capacitor (C SWT ) between SWT and GND. Fornormal mode operation, calculate the watchdog time-out capacitor as follows:C SWT = t WD /(5.06 x 106),with t RP in seconds and C SRT in Farads.F or the MAX6752 and MAX6753 windowed watchdog function, calculate the slow watchdog period, t WD2as follows:t WD2= 0.65 x 109x C SWTC SRT and C SWT must be a low-leakage (<10nA) type capacitor. Ceramic capacitors are recommended.Transient ImmunityIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these supervi-sors are relatively immune to short-duration supply tran-sients (glitches). The Maximum Transient Duration vs.Reset Threshold Overdrive graph in the Typical Operating Characteristics shows this relationship.The area below the curves of the graph is the region in which these devices typically do not generate a reset pulse. This graph was generated using a falling pulse applied to V CC , starting above the actual reset threshold (V TH ) and ending below it by the magnitude indicated (reset-threshold overdrive). As the magnitude of the tran-sient increases (farther below the reset threshold), the maximum allowable pulse width decreases. Typically, a V CC transient that goes 100mV below the reset threshold and lasts 50µs or less does not cause a reset pulse to be issued.µP Reset Circuits with Capacitor-Adjustable Reset/Watchdog Timeout Delay 10______________________________________________________________________________________Figure 5. MAX6752/MAX6753 Window Watchdog DiagramInterfacing to Other Voltages forLogic Compatibility The open-drain RESET output can be used to interface to a µP with other logic levels. As shown in Figure6, the open-drain output can be connected to voltages from 0 to 6V.Generally, the pullup resistor connected to the RESET connects to the supply voltage that is being monitored at the IC’s V CC pin. However, some systems can use the open-drain output to level-shift from the monitored supply to reset circuitry powered by some other supply. Keep in mind that as the supervisor’s V CC decreases towards 1V, so does the IC’s ability to sink current at RESET. Also, with any pullup resistor, RESET is pulled high as V CC decays toward zero. The voltage where this occurs depends on the pullup resistor value and the voltage to which it is connected.Ensuring a Valid RESET Down to V CC= 0V(Push-Pull RESET)When V CC falls below 1V, RESET current sinking capabil-ities decline drastically. The high-impedance CMOS-logic inputs connected to RESET can drift to undeter-mined voltages. This presents no problems in most applications, since most µPs and other circuitry do not operate with V CC below 1V.In those applications where RESET must be valid downto 0V, add a pulldown resistor between RESET andGND for the MAX6746/MAX6748/MAX6750/MAX6752push/pull outputs. The resistor sinks any stray leakage currents, holding RESET low (Figure7). The value of the pulldown resistor is not critical; 100kΩis large enoughnot to load RESET and small enough to pull RESET to ground. The external pulldown can not be used with the open-drain reset outputs.MAX6746–MAX6753µP Reset Circuits with Capacitor-AdjustableReset/Watchdog Timeout Delay ______________________________________________________________________________________11M A X 6746–M A X 6753µP Reset Circuits with Capacitor-Adjustable Reset/Watchdog Timeout Delay 12______________________________________________________________________________________Table 2.

General DescriptionThe MAX6736–MAX6745 are low-power dual-/triple-voltage microprocessor (µP) supervisors. These devices assert a reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds. The integrated dual/triple supervisory circuits significantly reduce size and power compared to separate ICs or discrete com-ponents. The low supply current of 6µA makes these devices ideal for portable equipment.The MAX6736/MAX6737 are dual fixed-voltage µP supervisors with a manual reset input. The MAX6738/MAX6739 have one fixed and one adjustable reset threshold and a manual reset input. The MAX6740/MAX6743 are triple-voltage µP supervisors with two fixed and one user-adjustable reset threshold inputs.The MAX6741/MAX6744 are dual-voltage µP supervi-sors with a power-OK (POK) output ideal for power-supply sequencing. The MAX6742/MAX6745 monitor the primary V CC supply and have an independent power-fail comparator.The MAX6736–MAX6745 monitor I/O supply voltages (V CC 1) from 1.8V to 5.0V and core supply voltages (V CC 2) from 0.9V to 3.3V with factory-trimmed reset threshold voltage options (Table 1). An external adjustable RSTIN input option allows monitoring volt-ages down to 0.5V.A variety of push-pull or open-drain reset outputs along with manual reset input and power-fail input/output fea-tures are available (see the Selector Guide ). The MAX6736–MAX6745 are offered in a space-saving 5-pin SC70 package and operate over the -40°C to +85°C temperature range.ApplicationsFeatureso Dual-/Triple-Supply Reset Voltage Monitors o Precision Factory-Set Reset Thresholds for Monitoring from 0.9V to 5.0Vo Adjustable Reset Input Down to 0.488Vo 150ms and 1200ms (min) Reset Timeout Period Optionso V CC 1 Power-OK Output for Power-SupplySequencing Applications (MAX6741/MAX6744)o Power-Fail Input/Power-Fail Output (MAX6742/MAX6745)o 6µA Supply Current o Tiny SC70 PackageMAX6736–MAX6745Low-Power Dual-/Triple-Voltage SC70 µPSupervisory Circuits________________________________________________________________Maxim Integrated Products1Selector GuideOrdering Information19-2531; Rev 1; 4/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Note:The first “_ _” or “_” are placeholders for the threshold voltage levels of the devices.

These devices are optimized for systems that monitor two or three supply voltages. The reset output state is guaranteed to remain valid while either V CC 1 or V CC 2 is above 1.2V.Threshold LevelsThe MAX6736/MAX6737/MAX6740/MAX6741/MAX6743/MAX6744 input voltage threshold combinations are indi-cated by a two-letter code in Table 1. The MAX6738/MAX6739/MAX6742/MAX6745 input voltage thresholds are indicated by a one-letter code in Table 2. Contact the factory for the availability of other voltage thresholds.Reset OutputThe MAX6736–MAX6745 provide an active-low reset out-put (RESET ). RESET is asserted when the voltage at either V CC 1 or V CC 2 falls below the voltage threshold level, RSTIN drops below the threshold, or MR is pulled low. Once reset is asserted, it stays low for the reset time-out period. If V CC 1, V CC 2, or RSTIN goes below the reset threshold before the reset timeout period is completed,the internal timer restarts. The MAX6736/MAX6738/MAX6740/MAX6741/MAX6742 have open-drain reset out-puts, while the MAX6737/MAX6739/MAX6743/MAX6744/MAX6745 have push-pull reset outputs (Figure 1).The MAX6740/MAX6741/MAX6742 include a RESET output with a manual reset detect function. The open-drain RESET output has an internal 50k Ωpullup to V CC 1. The RESET output is low while the output is pulled to GND and remains low for at least the manual reset timeout period after the external GND pulldown isFigure 1. Timing DiagramMAX6736–MAX6745Low-Power Dual-/Triple-Voltage SC70 µPSupervisory Circuits______________________________________________________________________________________11released. The manual reset detect function is internally debounced for the t DEB timeout period, so the output can be connected directly to a momentary pushbutton switch, if desired (Figure 2).Manual Reset InputMany microprocessor-based products require manual reset capability, allowing the operator, a test techni-cian, or external logic circuitry to initiate a reset while the monitored supplies remain above their reset thresh-olds. The MAX6736–MAX6739 have a dedicated active-low MR input. The RESET is asserted low while MR is held low and remains asserted for the manual reset timeout period after MR returns high. The MR input has an internal 1.5k Ωpullup resistor to V CC 1and can be left unconnected if not used. MR can be driven with CMOS logic levels, open-drain/open-collector out-puts, or a momentary pushbutton switch to GND to cre-ate a manual reset function.Adjustable Input VoltageThe MAX6738/MAX6739 and MAX6740/MAX6743 pro-vide an additional input to monitor a second or third system voltage. The threshold voltage at RSTIN is typi-cally 488mV. Connect a resistor-divider network to the circuit as shown in Figure 3 to establish an externally controlled threshold voltage, V EXT_TH .V EXT_TH = 0.488V((R1 + R2) / R2)Low leakage current at RSTIN allows the use of large-valued resistors, resulting in reduced power consump-tion of the system.Power-Fail ComparatorPFI is the noninverting input to an auxiliary comparator. A 488mV internal reference (V TH -PFI ) is connected to the inverting input of the comparator. If PFI is less than 488mV, PFO is asserted low. PFO deasserts without a timeout period when PFI rises above the externally set threshold. Common uses for the power-fail comparator include monitoring for low battery conditions or a failing DC-DC converter input voltage (see the Typical Application Circuits ). The asserted PFO output can place a system in a low-power suspend mode or support an orderly system shutdown before monitored V CC voltages drop below the reset thresholds. Connect PFI to an exter-nal resistor-divider network as shown in Figure 4 to set the desired trip threshold. Connect PFI to V CC 1 if unused.Applications InformationInterfacing to the µP with Bidirectional Reset PinsMost microprocessors with bidirectional reset pins can interface directly to open-drain RESET output options.Systems simultaneously requiring a push-pull RESET output and a bidirectional reset interface can be in logic contention. To prevent contention, connect a 4.7k Ωresistor between RESET and the µP ’s reset I/O port as shown in Figure 5.Figure 2. MAX6740/MAX6741/MAX6742 Manual Reset Timing DiagramFigure 3. Monitoring an Additional VoltageM A X 6736–M A X 6745Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits 12______________________________________________________________________________________Adding Hysteresis to the Power-Fail ComparatorThe power-fail comparator has a typical input hystere-sis of 2.5mV. This is sufficient for most applications in which a power-supply line is being monitored through an external voltage-divider. If additional noise margin is desired, connect a resistor between PFO and PFI, asshown in Figure 6. Select the values of R1, R2, and R3such that PFI sees V TH-PFI (488mV) when V EXT falls to its power-fail trip point (V FAIL ) and when V EXT rises to its power-good trip point (V GOOD ). The hysteresis win-dow extends between the specified V FAIL and V GOOD thresholds. R3 adds the additional hysteresis by sink-ing current from the R1/R2 divider network when the PFO output is logic low and sourcing current into the network when PFO is logic high. R3 is typically an order of magnitude greater than R1 or R2.The current through R2 should be at least 1µA to ensure that the 10nA (max) PFI input current does not significant-ly shift the trip points. Therefore, for most applications:R2 < V TH-PFI / 1mA < 0.488V / 1mA < 488k ΩPFO is an open-drain output requiring an externalpullup resistor, R4. Select R4 to be less than 1% of R3.V GOOD = DESIRED V EXT GOOD VOLTAGE THRESHOLD V FAIL = DESIRED V EXT FAIL VOLTAGE THRESHOLD V PU = V PULLUP (FOR OPEN-DRAIN PFO )R2 = 488k Ω(FOR >1µA R2 CURRENT)R3 = (R1 x V PU ) / (V GOOD - V FAIL )R4 ≤0.01 x R3Power Sequencing ApplicationsMany dual-voltage processors/ASICs require specific power-up/power-down sequences for the I/O and core supplies.Power SupplyFigure 6. Adding Hysteresis to Power Fail for Push-Pull PFOMAX6736–MAX6745Low-Power Dual-/Triple-Voltage SC70 µPSupervisory CircuitsFunctional DiagramThe MAX6741/MAX6744 offer a V CC 1 POK (POK1) ideal for V CC 1-to-V CC 2 sequencing. POK1 remains low as long as V CC 1 is below its V TH 1 threshold. When V CC 1exceeds V TH 1 for the POK1 timeout period (t POKP ), the open-drain POK1 output is deasserted. The POK1 output can then enable the V CC 2 power supply (use an external POK1 pullup resistor). RESET is deasserted when both V CC 1 and V CC 2 remain above their selected thresholds for the reset timeout period (t RP ). The POK1 output can be used for I/O before core or core before I/O sequenc-ing, depending on the selected V CC 1/V CC 2 thresholds.See the Typical Application Circuit and Figure 1.Monitoring a Negative VoltageThe power-fail comparator can be used to monitor a negative supply voltage using the circuit shown in Figure 4. When the negative supply is valid, PFO is low.When the negative supply voltage drops, PFO goes high. The circuit ’s accuracy is affected by the PFI threshold tolerance, V CC , R1, and R2.Transient ImmunityThe MAX6736–MAX6745 supervisors are relatively immune to short-duration falling V CC transients (glitch-es). It is usually undesirable to reset the µP when V CC experiences only small glitches. The Typical Operating Characteristics show Maximum V CC 1/V CC 2Transient Duration vs. Reset Threshold Overdrive, for which reset pulses are not generated. The graph shows the maxi-mum pulse width that a falling V CC transient might typi-cally have without causing a reset pulse to be issued.As the amplitude of the transient increases, the maxi-mum allowable pulse width decreases. A 0.1µF bypass capacitor mounted close to the V CC pin provides addi-tional transient immunity.Chip InformationTRANSISTOR COUNT: 249PROCESS: BiCMOSM A X 6736–M A X 6745Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits 14______________________________________________________________________________________Selector Guide (continued)Typical Application CircuitsMAX6736–MAX6745Low-Power Dual-/Triple-Voltage SC70 µPSupervisory Circuits______________________________________________________________________________________15Pin ConfigurationsOrdering Information (continued)M A X 6736–M A X 6745Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
