APX809/810

3-PIN MICROPROCESSOR RESET CIRCUITS

General Description

Features

The APX809/810 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 powered circuits.

•

Push-PullRESET Active Low (APX809)

These circuits perform a single function: they assert a reset

signal whenever the V_CCsupply voltage declines below a preset

threshold, keeping it asserted for at least 240ms after V_CChas

risen above the reset threshold. Reset thresholds suitable for

operation with a variety of supply voltages are available. The

APX809/810 have push pull outputs. The APX809 have an active

low RESET output, while the APX810 has an active high

RESET output. The reset comparator is designed to ignore fast

transients on V_CC, and the outputs are guaranteed to be in the

correct logic state for V_CCdown to 1V. Low supply current makes

the APX809/810 ideal for use in portable equipment. The

APX809/810 is available in a 3-pin SOT23 and SOT23R

package.
