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.
