The PS**6 is a
combines all required functions for a single chip for Passive
Infrared (PIR)motion detector. Motion detection is signaled through
the push-pull REL / LED output. A digital input OEN enables REL
output. A LED output indicates whenever the PIR Signal is above the
selected threshold. The PS**6 interfaces directly to a PIR sensor
via a highimpedance differential input. The PS**6 interfaces
directly to up to two conventional PIR sensors via a highimpedance
differential input. The PIR signal is converted to a *5 bit digital
value on chip. The parameters for sensitivity and timing are set by
connecting the corresponding inputs to DC voltages. The voltage
levels on the inputs are converted to digital values with 7
bitresolution. All signal processing is performed digitally. The
PS**6 is SOP *4 package.
