NOT RECOMMENDED FOR NEW DESIGN USE APX803S APX803/D 3-PIN MICROPROCESSOR RESET CIRCUIT The APX803/D is 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 powered circuits. These circuits perform a single function they assert a reset signal on power up and whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for a fixed period of time after VCC has risen above the reset threshold. For the APX803D this period is a minimum of 1ms while for other APX803 variants it is at least 140ms. 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. The APX803 is available with different reset thresholds suitable for operation with a variety of supply voltages, however the APX803D is available with a 2.93V threshold voltage. The APX803/D have an open collector active low RESET output and compliment Diodes APX809/10 which have push-pull output stages. Low supply current makes the APX803/D ideal for use in portable equipment.
