AAT3526

PowerManagerTM PRODUCT DATASHEET AAT3526/7/8 MicroPowerTM Supervisory Circuit with Manual Reset General Description The AAT3526/7/8 PowerManager products are members of AnalogicTech’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 reliable, low-cost 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. T...
