MAX6711L/M/R/S/T/Z, 4-Pin SC70 Microprocessor MAX6712L/M/R/S/T/Z, Reset Circuits with Manual Reset Input MAX6713L/M/R/S/T/Z General Description Features Precision Monitoring of 2.5V, 3.0V, 3.3V, and 5.0V The MAX6711/MAX6712/MAX6713 are microprocessor Power-Supply Voltages (P) supervisory circuits used to monitor the power supplies in P and digital systems. They provide Fully Specified Over Temperature excellent circuit reliability and low cost by eliminating exter- Available in Three Output Configurations nal components and adjustments when used with Push-Pull RESET Output (MAX6711) +5.0V, +3.3V, +3.0V, or +2.5V-powered circuits. They Push-Pull RESET Output (MAX6712) also provide a debounced manual reset input. Open-Drain RESET Output (MAX6713) These circuits assert a reset signal whenever the V CC 140ms min Power-On-Reset Pulse Width supply voltage declines below a preset threshold or Manual Reset Input whenever manual reset is asserted. Reset remains 12A Supply Current asserted for at least 140ms after V has risen above CC the reset threshold or when manual reset is deasserted. Guaranteed Reset Valid to V = +1V CC Reset thresholds suitable for operation with a variety of Power-Supply Transient Immunity supply voltages are available. No External Components The MAX6713 has an open-drain output stage, while 4-Pin SC70 Package the MAX6711/MAX6712 have push-pull outputs. The MAX6713s open-drain RESET output requires a pull-up Ordering Information resistor that can be connected to a voltage higher than PART TEMP RANGE PIN-PACKAGE V . The MAX6711/MAX6713 have an active-low reset CC MAX6711 EXS-T -40C to +125C 4 SC70 output, while the MAX6712 has an active-high reset out- put. The reset comparator is designed to ignore fast MAX6711 EXS-T10 -40C to +125C 4 SC70 transients on V , and the outputs are guaranteed to CC MAX6712 EXS-T -40C to +125C 4 SC70 be in the correct logic state for V down to 1V. CC MAX6712 EXS-T10 -40C to +125C 4 SC70 Low supply current makes the MAX6711/MAX6712/ MAX6713 EXS-T -40C to +125C 4 SC70 MAX6713 ideal for use in portable equipment. These devices are available in a 4-pin SC70 package. MAX6713 EXS-T10 -40C to +125C 4 SC70 Note: These parts are offered in 2.5k or 10k reels and must Applications be ordered in 2.5k or 10k increments. Order MAX6711 EXS-T for 2.5k reels and MAX6711 EXS-T10 for 10k reels.
