RS-232 data transmission is guaranteed up to 250kbps with the MAX3188 and up to 1Mbps with the MAX3189.The MAX3188/MAX3189 transmitters are inverting level translators that convert CMOS-logic levels to 5V EIA/TIA-232 levels. They feature a shutdown input that reduces current consumption to only 1µA and forces the transmitter output into a high-impedance state. The MAX3188/MAX3189 transmitters have a standard inverting output.ApplicationsDiagnostic Ports Telecommunications Networking Equipment Set-Top Boxes Digital Cameras Hand-Held EquipmentFeatureso Small 6-Pin SOT23 Package o 150µA Supply Currento Shutdown Reduces Supply Current to 1µA o Guaranteed Data Rate1Mbps (MAX3189)250kbps (MAX3188)o Three-State RS-232 Transmitter Output o No External Components RequiredMAX3188/MAX31891Mbps, 1µA RS-232 Transmitters in SOT23-6________________________________________________________________Maxim Integrated Products 1Typical Operating Circuit19-1628; Rev 0; 2/00Pin ConfigurationOrdering InformationM A X 3188/M A X 31891Mbps, 1µA RS-232 Transmitters in SOT23-62_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +4.5V to +6V, V EE = -4.5V to -6V, T A = T MIN to T MAX , unless otherwise noted.

The transmitter input does not have a pull-up resistor and should be connected to GND if unused.ShutdownThe MAX3188/MAX3189 feature a shutdown input.Drive SHDN low to reduce the supply current to 1µA (max). Shutdown also forces TOUT into a high-impedance state that allows the signal line to be safely controlled by other transmitters. Drive SHDN high for normal operation.Power-Supply DecouplingI n most circumstances, 0.1µF bypass capacitors are adequate for power-supply decoupling. Connect the bypass capacitors as close to the IC as possible.Applications InformationPower-Supply SourcesThe MAX3188/MAX3189 require ±4.5V to ±6V dual supplies. For applications where these supply voltages are not present, a DC-DC converter must be added.Due to the devices’ low current consumption, a charge pump can provide the proper supply voltages and requires a minimal amount of board space and cost.When using another RS-232 device containing an internal regulated charge pump (Table 1), the MAX3188/MAX3189 may be powered from the internal charge pump (Figure 2). This eliminates the need for additional external DC-DC converters to generate the required ±4.5V to ±6V dual supplies.M A X 3188/M A X 31891Mbps, 1µA RS-232 Transmitters in SOT23-64_______________________________________________________________________________________Pin DescriptionNegative Supply Voltage V EE 5Positive Supply VoltageV CC6RS-232 Transmitter Output TOUT 4TTL/CMOS Transmitter Input TIN 3PIN GroundGND 2Active-Low Shutdown.

General DescriptionThe MAX6730–MAX6735 single-/dual-/triple-voltage microprocessor (µP) supervisors feature a watchdog timer and manual reset capability. The MAX6730–MAX6735 offer factory-set reset thresholds for monitor-ing voltages from +0.9V to +5V and an adjustable reset input for monitoring voltages down to +0.63V. The com-bination of these features significantly improves system reliability and accuracy when compared to separate ICs or discrete components.The active-low reset output asserts and remains asserted for the reset timeout period after all the monitored volt-ages exceed their respective thresholds. Multiple factory-set reset threshold combinations reduce the number of external components required. The MAX6730/MAX6731monitor a single fixed voltage, the MAX6732/MAX6733monitor two fixed voltages, and the MAX6734/MAX6735monitor two fixed voltages and one adjustable voltage. All devices are offered with six minimum reset timeout peri-ods ranging from 1.1ms to 1120ms.The MAX6730–MAX6735 feature a watchdog timer with an independent watchdog output. The watchdog timer prevents system lockup during code execution errors.A watchdog startup delay of 54s after reset asserts allows system initialization during power-up. The watch-dog operates in normal mode with a 1.68s delay after initialization. The MAX6730/MAX6732/MAX6734 provide an active-low, open-drain watchdog output. The MAX6731/MAX6733/MAX6735 provide an active-low,push-pull watchdog output.Other features include a manual reset input (MAX6730/MAX6731/MAX6734/MAX6735) and push-pull reset out-put (MAX6731/MAX6733/MAX6735) or open-drain reset output (MAX6730/MAX6732/MAX6734). The MAX6730–MAX6733 are offered in a tiny SOT23-6 package. The MAX6734/MAX6735 are offered in a space-saving SOT23-8 package.

The MAX6730–MAX6735 monitor one to three supply voltages in µP-based systems and assert an active-low reset output when any monitored supply voltage drops below its preset threshold. The output state remains valid for V CC 1 or V CC 2 greater than +0.8V.Threshold LevelsThe two-letter code in the Reset Voltage Threshold Suffix G uide (Table 1) indicates the threshold level combinations for V CC 1 and V CC 2.Reset OutputThe MAX6730–MAX6735 feature an active-low reset out-put (RST ). RST asserts when the voltage at either V CC 1 or V CC 2 falls below the voltage threshold level, V RSTIN drops below its threshold, or MR is driven low (Figure 1).RST remains low for the reset timeout period (Table 2)after V CC 1, V CC 2, and RSTIN increase above their respective thresholds and after MR releases high.Whenever V CC 1, V CC 2, or RSTIN go below the reset threshold before the end of the reset timeout period, the internal timer restarts. The MAX6730/MAX6732/ MAX6734provide an open-drain RST output, and the MAX6731/MAX6733/MAX6735 provide a push-pull RST output.Single-/Dual-/Triple-Voltage µP Supervisory Circuits with Independent Watchdog Output 8_______________________________________________________________________________________**Standard versions are shown in bold and are available in a D3 timeout option only. Standard versions require 2500-piece order increments and are typically held in sample stock. There is a 10,000-piece order increment on nonstandard versions.Other threshold voltages may be available; contact factory for availability.Table 2. Reset Timeout Period Suffix GuideManual Reset InputMany µP-based products require manual reset capabil-ity, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic low on MR asserts the reset output, clears the watchdog timer,and deasserts the watchdog output. Reset remains asserted while MR is low and for the reset timeout peri-od (t RP ) after MR returns high. An internal 50k Ωpullup resistor allows MR to be left open if unused. Drive MR with TTL or CMOS-logic levels or with open-drain/col-lector outputs. Connect a normally open momentary switch from MR to GND to create a manual reset func-tion; external debounce circuitry is not required.Connect a 0.1µF capacitor from MR to GND to provide additional noise immunity when driving MR over long cables or if the device is used in a noisy environment.Adjustable Input Voltage (RSTIN)The MAX6734/MAX6735 provide an additional high-impedance comparator input with a 626mV threshold to monitor a third supply voltage. To monitor a voltage higher than 626mV, connect a resistive-divider to the circuit as shown in Figure 2 to establish an externally controlled threshold voltage, V EXT_TH.MAX6730–MAX6735Single-/Dual-/Triple-Voltage µP Supervisory Circuits with Independent Watchdog Output_______________________________________________________________________________________9Figure 1. RST , WDO , and MR Timing DiagramFigure 2. Monitoring a Third VoltageM A X 6730–M A X 6735The RSTIN comparator derives power from V CC 1, and the input voltage must remain less than or equal to V CC 1. Low leakage current at RSTIN allows the use of large-valued resistors, resulting in reduced power con-sumption of the system.WatchdogThe watchdog feature monitors µP activity through the watchdog input (WDI). A rising or falling edge on WDI within the watchdog timeout period (t WD ) indi-cates normal µP operation. WDO asserts low if WDI remains high or low for longer than the watchdog timeout period. Floating WDI does not disable the watchdog timer.The MAX6730–MAX6735 include a dual-mode watch-dog timer to monitor µP activity. The flexible timeout architecture provides a long-period initial watchdog mode, allowing complicated systems to complete lengthy boots, and a short-period normal watchdog mode, allowing the supervisor to provide quick alerts when processor activity fails. After each reset event (V CC power-up, brownout, or manual reset), there is a long initial watchdog period of 35s (min). The long watchdog period mode provides an extended time for the system to power up and fully initialize all µP and system components before assuming responsibility for routine watchdog updates.The usual watchdog timeout period (1.12s min) begins after the initial watchdog timeout period (t WD-L ) expires or after the first transition on WDI (Figure 3). During nor-mal operating mode, the supervisor asserts the WDO output if the µP does not update the WDI with a valid transition (high to low or low to high) within the standard timeout period (t WD-S ) (1.12s min).Connect MR to WDO to force a system reset in the event that no rising or falling edge is detected at WDI within the watchdog timeout period. WDO asserts low when no edge is detected by WDI, the RST output asserts low, the watchdog counter immediately clears,and WDO returns high. The watchdog counter restarts,using the long watchdog period, when the reset timeout period ends (Figure 4).Ensuring a Valid RESET Output Down to V CC = 0The MAX6730–MAX6735 guarantee proper operation down to V CC = +0.8V. In applications that require valid reset levels down to V CC = 0, use a 100k Ωpulldown resistor from RST to GND. The resistor value used is not critical, but it must be large enough not to load the reset output when V CC is above the reset threshold. For most applications, 100k Ωis adequate. Note that this configuration does not work for the open-drain outputs of MAX6730/MAX6732/MAX6734.Single-/Dual-/Triple-Voltage µP Supervisory Circuits with Independent Watchdog Output 10______________________________________________________________________________________Figure 3. Watchdog Input/Output Timing Diagram (MR and WDO Not Connected)Applications InformationInterfacing to µPs with BidirectionalReset PinsMicroprocessors with bidirectional reset pins can inter-face directly with the open-drain RST output options.However, conditions might occur in which the push-pull output versions experience logic contention with the bidirectional reset pin of the µP. Connect a 10k Ωresis-tor between RST and the µP ’s reset I/O port to prevent logic contention (Figure 5).Falling V CC TransientsThe MAX6730–MAX6735 µP supervisors are relatively immune to short-duration falling V CC _ transients (glitch-es). Small glitches on V CC _ are ignored by the MAX6730–MAX6735, preventing undesirable reset pulses to the µP. The Typical Operating Characteristics show Maximum Transient Duration vs. Reset ThresholdMAX6730–MAX6735Single-/Dual-/Triple-Voltage µP Supervisory Circuits with Independent Watchdog Output______________________________________________________________________________________11Figure 4. Watchdog Input/Output Timing Diagram (MR and WDOConnected)Figure 5. Interfacing to µPs with Bidirectional Reset I/OM A X 6730–M A X 6735Overdrive, for which reset pulses are not generated.The graph was produced using falling V CC _ pulses,starting above V TH and ending below the reset thresh-old by the magnitude indicated (reset threshold over-drive). The graph shows the maximum pulse width that a falling V CC transient typically might have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e., goes further below the reset threshold), the maximum allowable pulse width decreases. A 0.1µF bypass capacitor mounted close to V CC _ provides additional transient immunity.Watchdog Software ConsiderationsSetting and resetting the watchdog input at different points in the program rather than “pulsing ” the watch-dog input high-low-high or low-high-low helps the watchdog timer closely monitor software execution.This technique avoids a “stuck ” loop, in which the watchdog timer continues to be reset within the loop,preventing the watchdog from timing out. Figure 6shows an example flow diagram in which the I/O dri-ving the watchdog input is set high at the beginning of the program, set low at the beginning of every subrou-tine or loop, and then set high again when the program returns to the beginning. If the program “hangs ” in any subroutine, the I/O continually asserts low (or high),and the watchdog timer expires, issuing a reset or interrupt.Single-/Dual-/Triple-Voltage µP Supervisory Circuits with Independent Watchdog Output 12______________________________________________________________________________________Figure 6.

MAX809 Series,MAX810 SeriesVery Low Supply Current3−Pin MicroprocessorReset MonitorsThe MAX809 and MAX810 are cost−effective system supervisor circuits designed to monitor V CC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.The reset output is driven active within 10 m sec of V CC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after V CC rises above the reset threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESET output. Both devices are available in SOT−23 and SC−70 packages.The MAX809/810 are optimized to reject fast transient glitches on the V CC line. Low supply current of 0.5 m A (V CC= 3.2 V) makes these devices suitable for battery powered applications.Features•Precision V CC Monitor for 1.5 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies•Precision Monitoring V oltages from 1.2 V to 4.9 V Availablein 100 mV Steps•Four Guaranteed Minimum Power−On Reset Pulse Width Available (1 ms, 20 ms, 100 ms, and 140 ms)•RESET Output Guaranteed to V CC = 1.0 V.•Low Supply Current•Compatible with Hot Plug Applications•V CC Transient Immunity•No External Components•Wide Operating Temperature: −40°C to 105°C•Pb−Free Packages are AvailableTypical Applications•Computers•Embedded Systems•Battery Powered Equipment•Critical Microprocessor Power Supply MonitoringV CCFigure 1.

Normalized Power−Up Reset vs.Temperature10050751.01.110050APPLICATIONS INFORMATIONV CC Transient RejectionThe MAX809 provides accurate V CC monitoring and reset timing during power−up, power−down, and brownout/sag conditions, and rejects negative−going transients (glitches) on the power supply line. Figure 13shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive which lies under the curve will not generate a reset signal. Combinations above the curve are detected as a brownout or power−down.Typically, transient that goes 100 mV below the reset threshold and lasts 5.0 m s or less will not cause a reset pulse.Transient immunity can be improved by adding a capacitor in close proximity to the V CC pin of the MAX809.Figure 13.

This means CMOS logic inputs to the Microprocessor will be floating at an undetermined voltage.Most digital systems are completely shutdown well above this voltage. However, in situations where RESET must bemaintained valid to V CC = 0 V , a pull−down resistor must be connected from RESET to ground to discharge stray capacitances and hold the output low (Figure 14). This resistor value, though not critical, should be chosen such that it does not appreciably load RESET under normal operation (100 k W will be suitable for most applications).Figure 14. Ensuring RESET Valid to V CC = 0 VProcessors With Bidirectional I/O PinsSome Microprocessor’s have bidirectional reset pins.Depending on the current drive capability of the processor pin, an indeterminate logic level may result if there is a logic conflict. This can be avoided by adding a 4.7 k W resistor in series with the output of the MAX809 (Figure 15). If there are other components in the system which require a reset signal, they should be buffered so as not to load the reset line.If the other components are required to follow the reset I/O of the Microprocessor, the buffer should be connected as shown with the solid line.Figure 15.

Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits
General Description
The MAX6736–MAX6745 are low-power dual-/triplevoltage 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 components. 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 supervisors with a power-OK (POK) output ideal for powersupply 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 CC1) from 1.8V to 5.0V and core supply voltages (VCC2) from 0.9V to 3.3V with factory-trimmed reset threshold voltage options (Table 1). An external adjustable RSTIN input option allows monitoring voltages down to 0.5V. A variety of push-pull or open-drain reset outputs along with manual reset input and power-fail input/output features 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.

Note: The first “_ _” or “_” are placeholders for the threshold voltage levels of the devices. Desired threshold levels are set by the part number suffix found in Tables 1 and 2. The “_” after the D is a placeholder for the reset timeout period suffix found in Table 3. For example, the MAX6736XKLTD3-T is a dual-voltage supervisor VTH1 = 4.625V, VTH2 = 3.075V, and a 150ms minimum reset timeout period. All devices are available in tape-and-reel only. There is a 2500-piece minimum order increment for standard versions (see Table 1). Sample stock is typically held on standard versions only. Nonstandard versions require a minimum order increment of 10,000 pieces. Contact factory for availability.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
