AAT3560/2/4 NanoPower Voltage Detector Features The AAT3560 Series of PowerManager™ products is a member of AATI's Total Power Management IC™ (TPMIC™) product family. These voltage detectors are ideal for monitoring voltage supplies in portable systems, where extended battery life is critical. They provide a low cost, reliable solution by eliminating several external components. The AAT3560 series operates by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold, the device output changes state depending upon configuration. When the input voltage rises above the threshold, the device output reverts back to the previous state. The AAT3560 series are available with three different output stages: AAT3560 push-pull active high output, AAT3562 push-pull active low output and AAT3564 open drain active low output. • • • • • The quiescent supply current is extremely low, typically 1µA , making it ideal for portable battery operated equipment. • • • • • • • • • • PowerManager™ 1.2V to 5.5V Input voltage range Operates down to 1.2V Extremely low quiescent current: less than 2µA High accuracy detection threshold: ±1.5% Monitor Power Supply Voltages • Fixed thresholds from 2.2V to 4.6V Available output configurations: • Open-drain output • CMOS active high output • CMOS active low output Temp range -40 to 85°C 3 pin SOT-23 package Applications The AAT3560/2/4 are available in a 3 pin SOT-23 package and are specified over -40 to 85°C operating temperature range..

The output signal will remain valid until the input voltage falls below the Minimum Operating Voltage of 1V. Below this value the output voltage is undefined. When the input voltage rises above the factory programmed threshold, the output signal will resume its inactive state.
