M2000C  
MOS (PTY) LTD.  
PIR Light Controller  
Microsystems On Silicon  
for 3-Wire Applications  
Member of ELMOS Semiconductor AG  
General Description___________  
Applications_________________  
The M2000C integrated circuit combines all required  
functions for a single chip Passive Infra Red (PIR) light  
controller.  
Outdoor and indoor motion sensor lights  
High end lighting switches  
Automatic bedroom night lights  
Energy saving  
It is designed for load switching with a TRIAC or a relay  
in 3 wire systems.  
Features_____________________  
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.  
Digital signal processing  
On chip rectifier and supply regulator  
Low power consumption  
Temperature compensation input  
Adjustable soft on/off switching (fading)  
Dimmer function  
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  
Inductive load switching  
Capacitive load on/off switching  
Four quadrant TRIAC driver  
Suitable for 115V/60Hz and 230V/50Hz applications  
Low TRIAC switching noise  
All signal processing is performed digitally.
