General Description
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.
The AAT351x family is designed to ignore fast neg-
ative transients on V
DD
and to ensure that reset
outputs remain valid down to 1V.
The AAT351x family is available in the Pb-free,
space-saving 5-pin SOT23 surface mount package
and is specified over the -40 to +85°C temperature
range.
