MOSDESIGN SEMICONDUCTOR CORP. PIR CONTROLLER FOR RELAY OR TRIAC APPLICATION PIR CONTROLLER M7622 DESCRIPTION The M7622 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 in 2 wire and 3 wire systems. 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.
