DESCRIPTION
The M7621 integrated circuit combines all required functions for a single chip Passive Infra Red (PIR) light controller. It is
designed for load switching with a transistor or a relay in 3 wire AC and DC 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, CDS 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
