Rev. 1.0
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
brightness, fade, daylight sensor and environment
temperature correction. The corresponding voltage
levels are converted to digital values with a 4 bit
resolution
