General Description
The AAT3532 PowerManager is a member of
AnalogicTech’s Total Power Management IC™
(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
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 a Pb-free, 8-pin SOP
package and is specified over the -40°C to +85°C
temperature range.
