APX810S-23SR-7

APX809S/810S 3-PIN MICRO POWER VOLTAGE DETECTOR Description Pin Assignments The APX809S/810S are used for microprocessor (µP) supervisory circuits to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V and +2.5V powered circuits. (Top View) 2 Features             RESET/ RESET VCC 3 These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 240ms after V CC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The APX809S/810S have push pull outputs. The APX809S has an active low RESET output, while the APX810S has an active high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the APX809S/810S ideal for use in portable equipment. The APX809S/810S is available in a 3-pin SOT23 package.
