The PT8A2641WEX is a CMOS LSI chip designed for automatic PIR lamp control, suitable for both triac and relay applications. It operates at a typical voltage of 5V with an average supply current of 120µA. The device features a two-stage operational amplifier for filtering, a built-in noise rejection circuit, and an on-chip regulator. It includes an adjustable output duration and an override function, allowing for flexible operation modes: ON, AUTO, and OFF, selectable via the MODE pin. This chip is capable of detecting infrared variations caused by human motion, converting these variations into voltage changes to control lighting. It supports AC operation at 220V/50Hz and 110V/60Hz, and includes a zero-crossing detection feature for enhanced performance. The PT8A2641WEX also has a quick check mode for installation and an auto-reset function if the zero-cross signal is lost for over three seconds. The device is packaged in a 16-pin SOIC format, making it suitable for compact designs.
