CS9803
DESCRIPTION
CS9803 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 users' choice. With special noise immunity technique, CS9803 is the most stable PIR controller you can find on the market. More than this, there are few ponents needed in its application circuit which can reduce material cost and increase petitive.
CS9803 PIN DESCRIPTION
Pin No. 1 2 3 4 5 6 Pin Name UOU1 NII 1 II 1 VREF GND TB I/O Description
First stage OP amp output First stage OP amp positive input First stage OP amp negative input Stable reference voltage System ground Time base for 1. The delay time of receiving PIR singnal to sent a puls to trigger TRIAC or a high signal to trigger relay. The delay time = R x C x 32. The PIR signal patented and accepted only if the signal cycle greater than R x C x 768 .When state of relay or TRIAC is changing form active into inactive mode. It takes more...
