NanoPower Voltage Detector General Description
The AAT3560 Series of PowerManagerTM products is a member of AATI's Total Power ManagementTM IC (TPM ICTM) 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 1A , making it ideal for portable battery operated equipment. The AAT3560/2/4 are available in a 3 pin SOT-23 package and are specified over -40 to 85C operating temperature range..

Functional Description
General
The AAT3560 series of Nanopower voltage detectors, monitors a system power supply and asserts an output signal (Low for AAT3562, AAT3564 and High for AAT3560) when the supply voltage drops below a factory programmed threshold voltage. The output signal will remain valid until the input
VIN
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. An active noise-suppression circuit in the AAT3560/2/4 gives the output excellent immunity from power supply transients. See graph titled "Maximum Transient Duration vs. Reset Threshold Overdrive" for further information.
