Datasheet for Skyworks' AAT3532 PowerManager, a reset circuit for microprocessors with watchdog and voltage monitoring.
The AAT3532 is a fully integrated PowerManager from Skyworks' TPMIC™ family, designed to monitor microprocessor activity, external reset, and power supply conditions. It ensures correct system start-up by holding the microprocessor in reset for a minimum of 250ms while VCC is established. Features include an adjustable voltage monitor, programmable watchdog timer, low quiescent current, and a debounced manual reset input. The device is available in a Pb-free 8-pin SOP package and operates over -40°C to +85°C.
| Reset Pulse Width | 250ms (min) |
|---|---|
| Quiescent Current | Typically 23µA |
| Watchdog Timer Options | 150ms, 600ms, or 1200ms |
| Package Type | 8-pin SOP |
The device holds the microprocessor in a reset condition for a minimum of 250ms while VCC is established.
The quiescent supply current is extremely low, typically 23µA.
The AAT3532 includes a watchdog timer with programmable options of 150ms, 600ms, or 1200ms.
