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
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.
