With special noise immunity technique, LP8072C 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.  \nLP8072C PIN DESCRIPTION  \n| Pin\u003Cbr>No. | Pin Name | I/O | Description |\n| --- | --- | --- | --- |\n| 1 | UOU1 |  | First stage OP amp output |\n| 2 | NII 1 |  | First stage OP amp positive input |\n| 3 | II 1 |  | First stage OP amp negative input |\n| 4 | VREF |  | Stable reference voltage |\n| 5 | GND |  | System ground |\n| 6 | TB |  | Time base for 1. The delay time of receiving PIR singnal to sent a puls to t rigger TRIAC or a high signal to t rigger 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 than R x Cx 4069, then system is able to receive PIR signal again. 2.The flash cycle show the beginning of auto mode. Note: Width of TRIAC pulse = R x C x 2.
