AP1701/2/3/4

3-PIN MICROPROCESSOR RESET CIRCUITS

General Description

Features

The AP1701/2/3/4 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.

Available in three Output Configurations

•

Push-PullRESET Low Output (AP1701/3)

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

AP1701/2/3/4 have push pull outputs. The AP1701/3 have an

active low RESET output, while the AP1702/4 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 AP1701/2/3/4 ideal for use in portable equipment. The

AP1701/2/3/4 is available in a 3-pin SC59 package.
