General Description
The AAT351x PowerManager™ products are
members
Management IC™ product family. This family of
Microprocessor Reset Circuits provides the ulti-
mate in versatility, allowing system designers full
customization 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
The AAT351x family is designed to ignore fast neg-
ative transients on V
outputs remain valid down to 1V.
The AAT351x family is available in the space saving
5-pin SOT23 surface mount package and is speci-
fied over the -40 to +85°C temperature range.
