It is designed for load switching with a TRIAC in 2 wire and 3 wire systems. A conventional PIR sensor connects directly to the PIRIN input. The pull-down resistors 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.
