AAT3524

The AAT3520 Series of PowerManager products (which includes the AAT3522 and AAT3524) are part of AnalogicTech Total Power Management IC (TPM IC) product family. These microprocessor reset circuits AAT3524 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 AAT3520 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 V_CC has risen back above the fixed threshold; 30ms and 150ms minimum periods are available. The AAT3520 product series is guaranteed to operate down to 1.2V and designed to ignore fast line transients appearing on V_CC. The AAT3520 series is available with three output stage versions: AAT3520 push-pull active high output; AAT3522 push-pull active low output; and AAT3524 open drain active low output. The quiescent supply current is extremely low, typically 1A, making it ideal for portable battery-operated equipment. The AAT3520 series of products are available in a 3-pin SOT23 package and are specified over the -40 to +85C operating temperature range.
