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.
