The AAT3532 PowerManagerTM product is a member of AATI's Total Power Management ICsTM (TPMICTM) 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 condition for a minimum of 250ms while VCC is established 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 periodic strobe input from the microprocessor to ensure correct operation. The AAT3532 has a programmable watchdog timer and voltage tolerance level. The quiescent supply current is extremely low, typically 23A.
