MicroPower Microprocessor Reset Circuit with Delay

Manufacturer's part number :


Manufacturer Skyworks


Description :

The AAT352x series of PowerManager products is part of Skyworks' Total Power Management IC (TPMIC™) product family. These microprocessor reset circuits are ideal for monitoring voltage supplies in portable systems, where extended battery life is critical. They provide a low-cost, reliable solution by eliminating the need for external components. The AAT352x series operates by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold, the device asserts a reset signal for a fixed time period after VCC has risen back above the fixed threshold; 30ms and 150ms minimum periods are available. The AAT352x product series is guaranteed to operate down to 1.2V and is designed to ignore fast line transients appearing on VCC. The AAT352x series is available with two output stage versions: AAT3522 push-pull active low output; and AAT3524 open drain active low output. The quiescent supply current is extremely low, typically 1μA, making it ideal for portable battery-operated equipment. The AAT3522/3524 are available in a Pb-free, 3-pin SOT23 package and are specified over the -40°C to +85°C operating temperature range.
