AAT3526,pdf datasheet(MicroPow

The AAT3526/7/8 PowerManager products are membersof AnalogicTech’s Total Power Manage ment IC™ (TPMIC™)product family. These micro processor reset circuits are
ideal for monitoring voltage supplies in portable systems,where extended battery life is critical. They providea reliable, low-cost solution by eliminating externalcomponents. The AAT3526/7/8 products operate bymonitoring the system power supply voltage. When the
input voltage drops below a fixed threshold, the deviceasserts a reset signal for a minimum of 150ms after VCChas risen back above the fixed threshold. They are guaranteedto operate down to 1.2V and designed to ignorefast 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-pullactive high output; and AAT3528 open drain active lowoutput. The quiescent supply current is extremely low,typically 1μA, making this device ideal for portable battery-operated equipment.
