Description

The AAT3526/7/8 PowerManager™ products are members of AATI's 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 external components. The AAT3526/7/8 products 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 minimum of 150ms after VCC has risen back above the fixed threshold. They are guaranteed to operate down to 1.2V and designed to ignore fast line transients appearing on VCC. The AAT3526/7/8 series is available with three output stage versions: AAT3526 push-pull active low output, AAT3527 push-pull active high output and AAT3528 open drain active low output.

The quiescent supply current is extremely low, typically 1A, making this device ideal for portable battery operated equipment. The AAT3526/7/8 are available in a 4 pin SOT143 package and are specified over -40° to 85°C operating temperature range.
