Analogic AAT3562IGY-330-T1 Nanopower voltage detector Datasheet

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.

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
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.
