General Description

Features

The AAT351x PowerManager products are mem-

bers of AnalogicTech's Total Power Management

IC™ (TPMIC™) product family. This family of

microprocessor reset circuits provides the ultimate

in versatility, allowing system designers full cus-

tomization of the µP monitor and reset function

without any additional components. The AAT351x

family offers several combinations of threshold

voltage, watchdog timeout period, reset active peri-

od, and output drive configurations, which are all

factory-programmed options. All devices are avail-

able in 32 reset threshold voltages from 2.6V up to

5V, with three watchdog timeout periods from

6.3ms to 1600ms and three reset timeouts from

1ms up to 140ms. Available output configurations

are active low push-pull, active low open drain,

active low bi-directional, and active high push-pull.
