M2000C
PIR Light Controller
for 3-Wire Applications
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.
Applications_________________
♦ Outdoor and indoor motion sensor lights
♦ High end lighting switches
♦ Automatic bedroom night lights
♦ Energy saving
Features_____________________
♦ Digital signal processing
♦ On chip rectifier and supply regulator
♦ Low power consumption
♦ Temperature compensation input
♦ Adjustable soft on/off switching (fading)
♦ Dimmer function
♦ Inductive load switching
♦ Capacitive load on/off switching
♦ Four quadrant TRIAC driver
♦ Suitable for 115V/60Hz and 230V/50Hz applications
♦ Low TRIAC switching noise
