AAT3524IGY-2.93-200-T1

Processor Supervisor 2.93V 1 Active Low/Open Drain 3Pin SOT-23 T/R

The AAT3522 and AAT3524 are part of AnalogicTech’s Total Power Management™ IC TPM IC™ 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 external components. The AAT3522/AAT3524 operate 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 V CC has risen back above the fixed threshold; 30ms and 150ms minimum periods are available. The AAT3522/AAT3524 are guaranteed to operate down to 1.2V and designed to ignore fast line transients appearing on V CC . The AAT3522/AAT3524 are 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/AAT3524 are available in a 3-pin SOT23 package and are specified over the -40°C to +85°C operating temperature range.
