MOS (PTY) LTD. Microsystems On Silicon Member of ELMOS Semiconductor AG PIR CONTROLLER INTEGRATED CIRCUIT E931.97 PRELIMINARY INFORMATION - JUL 28, 2011 General Description Features Digital signal processing The E931.97 integrated circuit combines all required On chip supply shunt regulator functions for a single chip Passive Infra Red (PIR) motion Low power consumption detector. Motion detection is signaled through the push- Differential PIR sensor input pull REL output. A digital input OEN enables REL output. Excellent power supply rejection A LED output indicates whenever the PIR Signal is above Insensitive to RF interference the selected threshold. The E931.97 interfaces directly Inputs for sensitivity, on time and daylight sensor with up to two conventional PIR sensors via a high im- Outputs for relay and LED pedance differential input. The PIR signal is converted to Instantaneous settling after power up a 15 bit digital value on chip. The parameters for sensitiv- ity and timing are set by connecting the corresponding inputs to DC voltages. The voltage levels on the inputs Applications are converted to digital values with 7 bit resolution. All PIR motion detection signal processing is performed digitally. The E931.97 is Intruder detection available in TSSOP-14 and SOIC14 packages.
