General Description___________
The M2000C integrated circuit combines all required
functions for a single chip Passive Infra Red (PIR) light
controller.
It is designed for load switching with a TRIAC or a relay
in 3 wire systems.
A conventional PIR sensor connects directly to the PIR
input. The pull-down resistor and DC decoupling
circuitry are integrated on chip. The PIR signal is
converted to a 15 bit digital value.
External potentiometers or resistors are used to set the
operating
parameters
for
sensitivity,
on-time,
brightness, fade, daylight sensor and environment
temperature correction. The corresponding voltage
levels are converted to digital values with a 4 bit
resolution
All
signal
processing
is
performed
digitally.
