Overview
AAT3532 MicroPower™ Microprocessor Reset Circuit General Description The AAT3532 PowerManager™ product is a member 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 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 23µA.
The AAT3532 is available in an 8-pin SOP package specified over -40° to 85°C temperature range.
