The AAT3526/7/8 PowerManager products are membersof AnalogicTech’s Total Power Manage ment IC™ (TPMIC™)product family. These micro processor reset circuits areideal 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 theinput 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 AAT3526/7/8series 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.
