| MOSDESIGN SEMICONDUCTOR CORP. PIR CONTROLLER M7612 PIR CONTROLLER GENERAL DESCRIPTION The M7612 is a PIR ( passive infra-red ) controller , using analog mixing digital design technique and manufactures by CMOS Process which can either drive TRIAC or RELAY depending on user's choice. With special noise immunity technique , M7612 is the most stable PIR controller you can find on the market. More than this , there are few components needed in its application circuit which can reduce material cost and increase competitive. FEATURES High noise immunity. Drive either RELAY or TRIAC. Adjustable light on duration. TRIAC can be either shunt or serial connected. PIR input. CDS input. Auto change on / auto mode by bonding option. 16 pin DIP or SOP package. APPLICATIONS PIR light controller, Motion Detector, Alarm system, Auto-door bell.

Stable reference voltage. System ground. Time base for The delay time of receiving PIR signal to sent a pulse to trigger TRIAC or a high signal to trigger relay. The delay time = R * C * 32. 6 TB The PIR signal patented and accepted only if the signal cycle greater than R * C * 768. When state of RELAY or TRIAC is changing form active into inactive mode. It takes more than R * C * 4069 , then system is able to receive PIR signal again. 10K < R < 1M Ohm 100p F C < 0.1uf ( Reference Diagram 1 ) 7 QTEST For testing only. To set up the timing of how long TRIAC or RELAY is active. During the period , if the system receives the PIR signal , then it restarts counting the timing again. The flash cycle show the beginning of auto mode. 8 TCI Notewidth of TRIAC pulse = R * C * 2 Flash cycleR * C * 32768 The range for R4.7K R < 1M Ohm C100pF < C < 0.1uF ( Reference Diagram 2 ) Connected to a CDS for inhibiting RELAY or TRIAC being triggered. 9 CDS If TRIAC or RELAY has already being triggered by PIR signal and turned into active mode , then CDS can not inhibit PIR again. To trigger TRIAC , active low. 10 TRAIC Sink current15 mA max. To drive relay , active hign. 11 RELAY Sink current10 mA max.
