V PK vs. T AFAN6961 — Boundary Mode PFC ControllerFunctional DescriptionError AmplifierThe inverting input of the error amplifier is referenced to INV. The output of the error amplifier is referenced to COMP. The non-inverting input is internally connected to a fixed 2.5V ± 2% voltage. The output of the error amplifier is used to determine the on-time of the PWM output and regulate the output voltage. To achieve a low input current THD, the variation of the on time within one input AC cycle should be very small. A multi-vector error amplifier is built in to provide fast transient response and precise output voltage clamping.For FAN6961, connecting a capacitance, such as 1µF, between COMP and GND is suggested. The error amplifier is a trans-conductance amplifier that converts voltage to current with a 125µmho.Startup CurrentTypical startup current is less than 20µA. This ultra-low startup current allows the usage of high resistance, low-wattage start-up resistor. For example, 1M Ω/0.25W startup resistor and a 10µF/25V (V CC hold-up) capacitor are recommended for an AC-to-DC power adaptor with a wide input range 85-265V AC .Operating CurrentOperating current is typically 4.5mA. The low operating current enables a better efficiency and reduces the requirement of V CC hold-up capacitance.Maximum On-Time OperationGiven a fixed inductor value and maximum output power, the relationship between on-time and line voltage is:η•••=22rms o on V P L t(1)If the line voltage is too low or the inductor value is too high, t ON is too long. To avoid extra low operating frequency and achieve brownout protection, the maximum value of t ON is programmable by one resistor, R I , connected between MOT and GND. A 24k Ω resistor R I generates corresponds to 25µs maximum on time: ()s k R t I on μ2425)((max)•Ω= (2)The range of the maximum on-time is designed as 10 ~ 50µs.Peak Current LimitingThe switch current is sensed by one resistor. The signal is feed into CS pin and an input terminal of a comparator. A high voltage in CS pin terminates a switching cycle immediately and cycle-by-cycle current limit is achieved. The designed threshold of the protection point is 0.82V.Leading-Edge Blanking (LEB)A turn-on spike on CS pin appears when the power MOSFET is switched on. At the beginning of each switching pulse, the current-limit comparator is disabled for around 400ns to avoid premature termination. The gate drive output cannot be switched off during the blanking period. Conventional RC filtering is not necessary, so the propagation delay of current limit protection can be minimized.Under-Voltage Lockout (UVLO)The turn-on and turn-off threshold voltage is fixed internally at 12V/9.5V. This hysteresis behavior guarantees a one-shot start-up with proper start-up resistor and hold-up capacitor. With an ultra-low start-up current of 20µA, one 1M Ω R IN is sufficient for start-up under low input line voltage, 85V rms . Power dissipation on R IN would be less than 0.1W even under high line (V AC =265V rms ) condition.Output DriverWith low on resistance and high current driving capability, the output driver can drive an external capacitive load larger than 3000pF. Cross conduction current has been avoided to minimize heat dissipation, improving efficiency and reliability. This output driver is internally clamped by a 16.5V Zener diode.Zero-Current Detection (ZCD)The zero-current detection of the inductor is achieved using its auxiliary winding. When the stored energy of the inductor is fully released to output, the voltage on ZCD goes down and a new switching cycle is enabled after a ZCD trigger. The power MOSFET is always turned on with zero inductor current such that turn-on loss and noise can be minimized. The converter works in boundary mode and peak inductor current is always exactly twice of the average current. A natural power factor correction function is achieved with the low-bandwidth, on-time modulation. An inherent maximum off time is built in to ensure proper start-up operation. This ZCD pin can be used as a synchronous input.Noise ImmunityNoise on the current sense or control signal can cause significant pulse-width jitter, particularly in the boundary-mode operation. Slope compensation and built-in debounce circuit can alleviate this problem. Because the FAN6961 has a single ground pin, high sink current at the output cannot be returned separately. Good high-frequency or RF layout practices should be followed. Avoiding long PCB traces and component leads, locating compensation and filter components near to the FAN6961, and increasing the power MOSFET gate resistance improve performance.FAN6961 — Boundary Mode PFC ControllerReference CircuitFigure 14.

They provide excellent circuit reliability and low cost and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, with hysteresis keeping it asserted for time delay determined by externally pro-grammable time delay generator after V CC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.The G697L has an open-drain output stage, while the G696 have push-pull outputs. The G697L ’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than V CC . The G696L have an active-low RESET output, while the G696H has an active-high RESET output. The reset com-parator is designed to ignore fast transients on V CC , and the outputs are guaranteed to be in the correct logic state for V CC down to 0.8V.Low supply current makes the G696/G697 ideal for use in portable equipment.

The G697L/G696L/G696H assert reset to prevent code-execution errors during power-up,power-down, or brownout conditions. They assert areset signal whenever the V CC supply voltage declinesbelow a preset threshold (V TH-), keeping it asserted fortime delay set by capacitor connected to C D pin, after V CC has risen above the high reset threshold V TH+(V TH-+V HYS ). The G697L uses an open-drain output,and the G696L/G696H have a push-pull output stage.Connect a pull-up resistor on the G697L ’s RESET out-put to any supply between 0 and 5.5V. The time delay is set by external capacitor C D , and internal pull up current I CD . When the voltage at C D pin exceeds the buffer threshold, typically 1.25V, the RESET output high (RESET output low). The volt-age detector and buffer have built-in hysterisis to prevent erratic reset operation. The formula of time delay is T (ms) ≅ 1685 C D (µF). Fig1 and Fig2 show a timing deagram and a Functional Block.Figure3. RESET Valid to V CC = Ground CircuitEnsuring a Valid Reset Output Down to VCC = 0When V CC falls below 0.8V, the G696 RESET output no longer sinks current-it becomes an open circuit. Therefore, high-impedance CMOS logic inputs con-nected to RESET can drift to undetermined voltages. This presents no problem in most applications since most µP and other circuitry is inoperative with VCC below 0.8V. However, in applications where RESETmust be valid down to 0V, adding a pull-down resistor to RESET causes any stray leakage currents to flow to ground, holding RESET low (Figure 4). R1’s valueis not critical ; 100k Ω is large enough not to loadRESET and small enough to pull RESET to ground. A 100k Ω pull-up resistor to V CC is also recommended for the G697L if RESET is required to remain validfor V CC < 0.8V.Figure 4. Interfacing to µPs with Bidirectional Re-set I/OFigure 5. G697L Open-Drain RESET Output AllowsUse with Multiple SuppliesVInterfacing to µPs with Bidirectional Reset Pins Since the RESET output on the G697L is open drain, this device interfaces easily with µPs that have bidirec-tional reset pins, such as the Motorola 68HC11. Con-necting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 5).G697L Open-Drain RESET Output Allows Use with Multiple SuppliesGenerally, the pull-up connected to the G697L will connect to the supply voltage that is being monitored at the IC’s V CC pin. However, some systems may use the open-drain output to level-shift from the monitored supply to reset circuitry powered by some other supply (Figure 6). Note that as the G697L’s V CC decreases below 1V, so does the IC’s ability to sink current at RESET. Also, with any pull-up, RESET will be pulled high as VCC decays toward 0. The voltage where this occurs depends on the pull-up resistor value and the voltage to which it is connected.Benefits of Highly Accurate Reset ThresholdMost µP supervisor ICs have reset threshold voltages between 5% and 10% below the value of nominal supply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the supply is 10% below nominal.When using ICs rated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted.The G69_ _463/G69_ _308 use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal.Package InformationSOT-23-5 (T1) PackageNote:1.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- pow-ered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold. Reset thresholds suitable for operation with a variety of supply voltages are avail-able.The G671L has an open-drain output stage, while the G670 have push-pull outputs. The G671L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than V CC. The G670L have an active-low RESET output, while the G670H has an active-high RESET output. The reset com-parator is designed to ignore fast transients on V CC, and the outputs are guaranteed to be in the correct logic state for V CC down to 1V.Low supply current makes the G670/G671 ideal for use in portable equipment. The G670/G671 are avail-able in 3-pin SOT-23, TO-92 and SOT-89 packages.Pin Configuration Typical Application CircuitTopVCC*G671 only SOT-2312123SOT-89TO-92132ViewOrdering InformationORDER NUMBER ORDER NUMBER(Pb free)TEMP.

The G671L/G670L/G670H assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for at most 2ms after V CC has risen above the reset thresh-old. The G671L uses an open-drain output, and the G670L/G670H have a push-pull output stage. Connect a pull-up resistor on the G671L’s RESET output to any supply between 0 and 5.5V.Figure 1. Maximum Transient Duration Without Causing a Reset Pulse vs. Reset Com-parator OverdriveFigure 2. RESET Valid to V CC = Ground Circuit Applications InformationNegative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, the G671L/ G670H/G670L are relatively immune to short- duration negative-going V CC transients (glitches).Figure 1 shows typical transient duration vs. reset comparator overdrive, for which the G671L/G670H/ G670L do not generate a reset pulse. The graph was generated using a negative-going pulse applied to V CC, starting 0.5V above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). The graph indicates the maxi-mum pulse width a negative-going V CC transient can have without causing a reset pulse. As the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width de-creases. Typically, for the G67_ _463 and G67_ _438, a V CC transient that goes 100mV below the reset threshold and lasts 7µs or less will not cause a reset pulse. A 0.1µF bypass capacitor mounted as close as possible to the V CC pin provides additional transient immunity.Ensuring a Valid Reset Output Down to V CC = 0 When V CC falls below 1V, the G670 RESET output no longer sinks current—it becomes an open circuit. Therefore, high-impedance CMOS logic inputs con-nected to RESET can drift to undetermined voltages. This presents no problem in most applications since most µP and other circuitry is inoperative with VCC below 1V. However, in applications where RESET must be valid down to 0V, adding a pull-down resistor to RESET causes any stray leakage currents to flow to ground, holding RESET low (Figure 2). R1’s value is not critical; 100kΩ is large enough not to load RESET and small enough to pull RESET to ground.A 100kΩ pull-up resistor to VCC is also recommended for the G671L if RESET is required to remain valid for V CC< 1V.Figure 3. Interfacing to µPs with Bidirectional Re-set I/OFigure 4. G671L Open-Drain RESET Output Allows Use with Multiple Supplies Interfacing to µPs with Bidirectional Reset Pins Since the RESET output on the G671L is open drain, this device interfaces easily with µPs that have bidirec-tional reset pins, such as the Motorola 68HC11. Con-necting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 3).G671L Open-Drain RESET Output Allows Use with Multiple SuppliesGenerally, the pull-up connected to the G671L will connect to the supply voltage that is being monitored at the IC’s V CC pin. However, some systems may use the open-drain output to level-shift from the monitored supply to reset circuitry powered by some other supply (Figure 4). Note that as the G671L’s V CC decreases below 1V, so does the IC’s ability to sink current at RESET. Also, with any pull-up, RESET will be pulled high as VCC decays toward 0. The voltage where this occurs depends on the pull-up resistor value and the voltage to which it is connected.Benefits of Highly Accurate Reset ThresholdMost µP supervisor ICs have reset threshold voltages between 5% and 10% below the value of nominal supply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the supply is 10% below nominal.When using ICs rated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted.The G67_ _463/G67_ _308 use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal.VPackage InformationTO-92 (TD) PackageMILLIMETER INCH SYMBOLMIN MAX MIN MAXA 3.35 3.86 0.132 0.152 A1 1.0414 1.55 0.041 0.061 b 0.254 0.508 0.010 0.020 E 4.34 4.85 0.1710.191 C 0.254 0.508 0.010 0.020 L 14.53 15.04 0.572 0.592 e 1.143 1.397 0.045 0.055 G 3.683 4.191 0.145 0.165 D 4.29 4.80 0.169 0.189 D1 4.34 4.85 0.171 0.191SOT-89 (T2) PackageDIMENSIONS IN MILLIMETER DIMENSIONS IN INCH SYMBOLMIN NOM MAX MIN NOM MAXA 1.40 1.50 1.60 0.055 0.059 0.063 A1 0.80 1.04 ----- 0.031 0.041 -----b 0.36 0.42 0.48 0.014 0.016 0.018 b1 0.41 0.47 0.53 0.016 0.0180.020 C 038 0.40 0.43 0.014 0.015 0.017 D 4.40 4.50 4.60 0.173 0.177 0.181 D1 1.40 1.60 1.75 0.055 0.062 0.069 HE ----- ----- 4.25 ----- ----- 0.167 E 2.40 2.50 2.60 0.094 0.098 0.102 e 2.90 3.00 3.10 0.114 0.118 0.122Package InformationSOT-23 (T7) PackageNote:1.Package body sizes exclude mold flash protrusions or gate burrs2.Tolerance ±0.1000 mm (4mil) unless otherwise specified3.Coplanarity: 0.1000mm4.Dimension L is measured in gage planeDIMENSIONS IN MILLIMETERSYMBOLMIN NOM MAXA 1.00 1.10 1.30A1 0.00 ----- 0.10A2 0.70 0.80 0.90 b 0.35 0.40 0.50C 0.10 0.15 0.25D 2.70 2.90 3.10E 1.40 1.60 1.80e ----- 1.90(TYP) ----- H 2.60 2.803.00L 0.37 ------ ----- θ1 1° 5° 9°Taping SpecificationPACKAGE Q ’TY/REEL Q ’TY/BY BAGTO-92 ----- 2,000 ea SOT-89 1,000 ea ----- SOT-23 3,000 ea -----GMT Inc. does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and GMT Inc. reserves the right at any time without notice to change said circuitry and specifications.θ1A1SOT-89 Package OrientationSOT-23 Package Orientation。

STR-G6651中文资料
The STR-G6651 is specifically designed to satisfy the requirements for increased integration and reliability in off-line quasi-resonant flyback converters. This device incorporates the primary control and drive circuit with a discrete avalanche-rated power MOSFET.Cycle-by-cycle current limiting, under-voltage lockout with hyster-esis, over-voltage protection, and thermal shutdown protects the power supply during the normal overload and fault conditions. Over-voltage protection and thermal shutdown are latched after a short delay. The latch may be reset by cycling the input supply.

MOT VoltageFigure 14. Threshold Voltage for Peak Current LimitSG6961 — Critical Conduction Mode PFC ControllerFunctional DescriptionError AmplifierThe inverting input of the error amplifier is referenced to INV. The output of the error amplifier is referenced to COMP. The non-inverting input is internally connected to a fixed 2.5V ± 2% voltage. The output of the error amplifier is used to determine the on-time of the PWM output and regulate the output voltage. To achieve a low input current THD, the variation of the on time within one input AC cycle should be very small. A multi-vector error amplifier is built in to provide fast transient response and precise output voltage clamping.For SG6961, connecting a capacitance, such as 1µF, between COMP and GND is suggested. The error amplifier is a trans-conductance amplifier that converts voltage to current with a 125µmho.Startup CurrentTypical startup current is less than 20µA. This ultra-low startup current allows the usage of high resistance, low-wattage startup resistor. For example, 1 M Ω/0.25W startup resistor and a 10µF/25V (V CC hold-up) capacitor are recommended for an AC-to-DC power adaptor with a wide input range 85 to 265V AC .Operating CurrentOperating current is typically 4.5mA. The low operating current enables a better efficiency and reduces the requirement of V CC hold-up capacitance.Maximum On-Time OperationGiven a fixed inductor value and maximum output power, the relationship between on-time and line voltage is: η•••=2rms O ON V P L 2t(1)If the line voltage is too low or the inductor value is too high, t ON is too long. To avoid extra low operating frequency and achieve brownout protection, the maximum value of t ON is programmable by one resistor, R I , connected between MOT and GND. A 24k Ω resistor R I generates corresponds to 25µs maximum on time: ()µS 2425)k (R t I ONMAX •Ω= (2)The range of the maximum on-time is designed as 10 ~ 50µs.Peak Current LimitingThe switch current is sensed by one resistor. The signal is feed into CS pin and an input terminal of a comparator. A high voltage in CS pin terminates a switching cycle immediately and cycle-by-cycle current limit is achieved. The designed threshold of the protection point is 0.82V.Leading-Edge Blanking (LEB)A turn-on spike on CS pin appears when the power MOSFET is switched on. At the beginning of each switching pulse, the current-limit comparator is disabled for around 400ns to avoid premature termination. The gate drive output cannot be switched off during the blanking period. Conventional RC filtering is not necessary, so the propagation delay of current limit protection can be minimized.Under-Voltage Lockout (UVLO)The turn-on and turn-off threshold voltage is fixed internally at 12V/9.5V. This hysteresis behavior guarantees a one-shot startup with proper startup resistor and hold-up capacitor. With an ultra-low startup current of 20µA, one 1M Ω R IN is sufficient for startup under low input line voltage, 85V rms . Power dissipation on R IN would be less than 0.1W even under high line (V AC =265V rms ) condition.Output DriverWith low on resistance and high current driving capability, the output driver can drive an external capacitive load larger than 3000pF. Cross conduction current has been avoided to minimize heat dissipation, improving efficiency and reliability. This output driver is internally clamped by a 16.5V Zener diode.Zero-Current Detection (ZCD)The zero-current detection of the inductor is achieved using its auxiliary winding. When the stored energy of the inductor is fully released to output, the voltage on ZCD goes down and a new switching cycle is enabled after a ZCD trigger. The power MOSFET is always turned on with zero inductor current such that turn-on loss and noise can be minimized. The converter works in boundary mode and peak inductor current is always exactly twice of the average current. A natural power factor correction function is achieved with the low-bandwidth, on-time modulation. An inherent maximum off time is built in to ensure proper startup operation. This ZCD pin can be used as a synchronous input.Noise ImmunityNoise on the current sense or control signal can cause significant pulse-width jitter, particularly in the boundary-mode operation. Slope compensation and built-in debounce circuit can alleviate this problem. Because the SG6961 has a single ground pin, high sink current at the output cannot be returned separately. Good high-frequency or RF layout practices should be followed. Avoiding long PCB traces and component leads, locating compensation and filter components near to the FAN6961, and increasing the power MOSFET gate resistance improve performance.分销商库存信息:FAIRCHILDSG6961SZ SG6961DZ SG6961SY。

Connectors are fully shrouded, unsealed connectors for interconnecting cable-to-cable, cable-to-board and board-to-board applications.The Gecko Crimp variants are fully shrouded, unsealed connectors with replaceable contacts. They are designed for interconnecting cable-to-cable and cable-to-board. The housings have a low profile potting wall to allow back potting for additional strain relief and improved sealing where required. All pre-made cable assemblies are supplied back-potted for customer convenience, and individually crimped contacts are also available.There are three variants of the range, the ranges are not intermateable:•Gecko-SL – Screw-Lok version. Female connectors have floating screws for secure, robust interconnection to the male counterpart. Male Screw-Loks can also have board-mount studs forsecure PCB connection.•Gecko with Latches (original design). Male variants can be equipped with locking latches for secure interconnection with easy to release features. Latches can be specified with through board locking features or surface mount pads for additional security.•Gecko-MT. Connectors are equipped with both signal and power contacts and are available in crimped or through-board configurations. Screw-Lok technology is used to secure the connectors,and board-mount studs for PCB fastening are available.All contacts are gold plated all over for high performance and long service life; the contact plating is hard acid gold of 98% purity.The Gecko-SL and latched ranges cover 06, 10, 12, 16, 20, 26, 34 and 50 total number of contacts in a dual row configuration. Connector housings are polarised to prevent mis-matching and have contact position one indicated on the outside of the housings. Metal backshells are available for sizes 06, 10, 12 and 16 cable variants in the Gecko-SL range, to provide mechanical, RF and EMC protection. Gecko-MT connectors are available in ’01-08-01’ and ’02-08-02’ configurations, with 2 power contacts and 8 signal contacts or 4 power contacts and 8 signal contacts respectively.2. RATINGS2.1.

Microprocessor Reset ICFeaturesPrecision Monitoring of +3V, +3.3V, and +5VPower-Supply VoltagesFully Specified Over Temperature Available in Three Output ConfigurationsPush-Pull RESET Output (G696L) Push-Pull RESET Output (G696H) Open-Drain RESET Output (G697L)Externally Programmable Time Delay Generator 14µA Supply CurrentGuaranteed Reset Valid to V CC = 0.8V Power Supply Transient Immunity5 pin SOT-23-5 or TSOT-23-5 Packages 2% Threshold AccuracyApplicationsComputers ControllersIntelligent InstrumentsCritical µP and µC Power Monitoring Portable / Battery-Powered Equipment AutomotiveGeneral DescriptionThe G696/G697 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, with hysteresis keeping it asserted for time delay determined by externally pro-grammable time delay generator after V CC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.The G697L has an open-drain output stage, while the G696 have push-pull outputs. The G697L ’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than V CC . The G696L have an active-low RESET output, while the G696H has an active-high RESET output. The reset com-parator is designed to ignore fast transients on V CC , and the outputs are guaranteed to be in the correct logic state for V CC down to 0.8V.Low supply current makes the G696/G697 ideal for use in portable equipment. The G696/G697 are avail-able in 5-pin SOT23-5 or TSOT-23-5 packages.Pin Configuration Typical Application Circuit(RESET)RESET VCCSOT-23-5/TSOT-23-5NCGNDCD()is for G696H*G697 ONLYV COrdering InformationORDER NUMBER ORDER NUMBER(Pb free)TEMP.

The G697L/G696L/G696H assert reset to prevent code-execution errors during power-up,power-down, or brownout conditions. They assert areset signal whenever the V CC supply voltage declinesbelow a preset threshold (V TH-), keeping it asserted fortime delay set by capacitor connected to C D pin, after V CC has risen above the high reset threshold V TH+(V TH-+V HYS ). The G697L uses an open-drain output,and the G696L/G696H have a push-pull output stage.Connect a pull-up resistor on the G697L ’s RESET out-put to any supply between 0 and 5.5V. The time delay is set by external capacitor C D , and internal pull up current I CD . When the voltage at C D pin exceeds the buffer threshold, typically 1.25V, the RESET output high (RESET output low). The volt-age detector and buffer have built-in hysterisis to prevent erratic reset operation. The formula of time delay is T (ms) ≅ 1685 C D (µF). Fig1 and Fig2 show a timing deagram and a Functional Block.Figure3. RESET Valid to V CC = Ground CircuitEnsuring a Valid Reset Output Down to VCC = 0When V CC falls below 0.8V, the G696 RESET output no longer sinks current-it becomes an open circuit. Therefore, high-impedance CMOS logic inputs con-nected to RESET can drift to undetermined voltages. This presents no problem in most applications since most µP and other circuitry is inoperative with VCC below 0.8V. However, in applications where RESETmust be valid down to 0V, adding a pull-down resistor to RESET causes any stray leakage currents to flow to ground, holding RESET low (Figure 4). R1’s valueis not critical ; 100k Ω is large enough not to loadRESET and small enough to pull RESET to ground. A 100k Ω pull-up resistor to V CC is also recommended for the G697L if RESET is required to remain validfor V CC < 0.8V.Figure 4. Interfacing to µPs with Bidirectional Re-set I/OFigure 5. G697L Open-Drain RESET Output AllowsUse with Multiple SuppliesVInterfacing to µPs with Bidirectional Reset Pins Since the RESET output on the G697L is open drain, this device interfaces easily with µPs that have bidirec-tional reset pins, such as the Motorola 68HC11. Con-necting the µP supervisor’s RESET output directly to the microcontroller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 5).G697L Open-Drain RESET Output Allows Use with Multiple SuppliesGenerally, the pull-up connected to the G697L will connect to the supply voltage that is being monitored at the IC’s V CC pin. However, some systems may use the open-drain output to level-shift from the monitored supply to reset circuitry powered by some other supply (Figure 6). Note that as the G697L’s V CC decreases below 1V, so does the IC’s ability to sink current at RESET. Also, with any pull-up, RESET will be pulled high as VCC decays toward 0. The voltage where this occurs depends on the pull-up resistor value and the voltage to which it is connected.Benefits of Highly Accurate Reset ThresholdMost µP supervisor ICs have reset threshold voltages between 5% and 10% below the value of nominal supply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the supply is 10% below nominal.When using ICs rated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted.The G69_ _463/G69_ _308 use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal.Package InformationSOT-23-5 (T1) PackageNote:1.
