PowerManager
General Description
The AAT3532 PowerManager product is a mem-
ber of AATI’s Total Power Management ICs
(TPMIC) product family. It is a fully integrated
device for monitoring microprocessor activity,
external reset, and power supply conditions. The
device holds the microprocessor in a reset condi-
tion for a minimum of 250ms while V
CC
is estab-
lished to ensure correct system start-up. A manual
reset can be initiated via a de-bounced input pin.
As an additional level of protection, the AAT3532
includes a watchdog timer which requires a period-
ic strobe input from the microprocessor to ensure
correct operation. The AAT3532 has a programma-
ble watchdog timer and voltage tolerance level.
The quiescent supply current is extremely low, typ-
ically 23μA.
The AAT3532 is available in an 8-pin SOP package
specified over -40° to 85°C temperature range.
