NCS36000

Passive Infrared (PIR)
Detector Controller

The NCS36000 is a fully integrated mixed−signal CMOS device

designed for low−cost passive infrared controlling applications. The
device integrates two low−noise amplifiers and a LDO regulator to
drive the sensor. The output of the amplifiers goes to a window
comparator that uses internal voltage references from the regulator.
The digital control circuit processes the output from the window
comparator and provides the output to the OUT and LED pin.
