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 Note：width of TRIAC pulse = R * C * 2 Flash cycle：R * C * 32768 The range for R：4.7K ≦ R < 1M Ohm C：100pF < C < 0.1uF ( Reference Diagram 2 ) Connected to a CDS for inhibiting RELAY or TRIAC being triggered. 9 CDS 10 TRAIC 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. Sink current：15 mA max. To drive relay , active hign. 11 RELAY Sink current：10 mA max. Source current：10 mA max. 12 ZCD Detect zero cross of AC line under remote mode function. 13 VDD Operation voltage：5V , stand by current：0.5 mA 14 II2 2 nd stage OP amp negative input. 15 NII2 2 nd stage OP amp positive input. 16 UOU2 2 nd stage OP amp output. 2/9 2007-05-29 一华半导体股份有限公司 PIR CONTROLLER MOSDESIGN SEMICONDUCTOR CORP.
