NanoPower™ Voltage Detector

PowerManager
General Description
Features
The AAT3560/2/4 series of PowerManager prod-
ucts are part of AnalogicTech'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 exter-
nal 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 con-
figuration. When the input voltage rises above the
threshold, the device output reverts back to the pre-
vious state. The AAT3560 series is 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.

falls below the minimum operating voltage of 1V.
Below this value, the output voltage is undefined.
When the input voltage rises above the factory-pro-
grammed threshold, the output signal will resume
its inactive state. An active noise-suppression cir-
cuit 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.
Functional Description
General
The AAT3560 series of NanoPower voltage detec-
tors monitor a system power supply and assert an
output signal (low for AAT3562 and AAT3564; high
for AAT3560) when the supply voltage drops below
a factory-programmed threshold voltage. The out-
put signal will remain valid until the input voltage
