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.
FEATURES
Digital signal processing
On chip rectifier and supply regulator
Temperature compensation input
Adjustable soft on/off switching (fading)
Light modeIncrease lamp brightness from set brightness to full brightness on movement.
Light modeIncrease lamp brightness from off to set brightness on movement.
Dimmer function
Inductive load switching
Drive either RELAY or TRIAC
Suitable for 115V/60Hz and 230V/50Hz applications
