PT8A2612 Description
The PT8A2612 is a CMOS LSI chip based on 260 base designed for use in automatic PIR lamp control. It can operate with a 2-wire configuration for triac applications with dimmer function or 3-wire configuration for RELAY application. Its PIR sensor detects infrared power variations induced by the motion of a human body and transforms it to a voltage variation.
