AAT3532

DATA SHEET AAT3532 MicroPowerTM Microprocessor Reset Circuit General Description The AAT3532 PowerManager is a member of Skyworks' 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 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 a Pb-free, 8-pin SOP package and is specified over the -40°C to +85°C temperature range. Features Adjustable 4.5V or 4.75V Voltage Monitor 250ms (min)...
