AAT3560/2/4
NanoPower Voltage Detector
™
PowerManager
General Description
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.
