PT8A2641WEX

Sensor And Detector Interfaces Overview

The PT8A2641WEX is a CMOS LSI chip designed for automatic PIR lamp control, operating at a typical voltage of 5V with an average supply current of 120µA. It features a two-stage operational amplifier for filtering and a built-in noise rejection circuit. The device includes an on-chip regulator providing approximately 3.6V output. It supports adjustable output duration via external RC components connected to the OSCD pin. The chip offers selectable operating modes (ON/AUTO/OFF) through the MODE pin and provides an override function. It is compatible with AC 220V/50Hz and 110V/60Hz power lines. The WEX suffix indicates a lead-free, green SOIC-16 package in tape and reel format.

Sensor And Detector Interfaces Feature Summary

Integrated two-stage operational amplifier and comparator for signal processing
Built-in noise rejection circuit and zero-crossing detection
Selectable operating modes including ON, AUTO, and OFF states
Override functionality allowing manual control during operation

Sensor And Detector Interfaces Applications

Automatic PIR lamp control systems
AC line-powered lighting switches
Motion-sensing security lighting

Sensor And Detector Interfaces Procurement Notes

Verify that the ordering suffix 'WEX' corresponds to the specific SOIC-16 package and tape-and-reel configuration required for your assembly process. Confirm compatibility with your manufacturing equipment for surface-mount placement. Ensure the component meets environmental standards such as lead-free and green specifications as indicated by the manufacturer's designation.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring integrated PIR sensor signal conditioning and direct drive capabilities for TRIACs or relays. Consider the PT8A2642WEX if a relay drive output is preferred over the TRIAC pulse output provided by the PT8A2641WEX. Evaluate the need for the override function and adjustable timing features when designing the user interface and control logic for the lighting system.

Sensor And Detector Interfaces Part Context

The PT8A2641WEX belongs to the PT8A264X family of PIR sensor light switch controllers manufactured by Diodes Incorporated, formerly Pericom Semiconductor. This family includes variants like the PT8A2642WEX, which differ primarily in their output stage configuration. The PT8A2641 variant specifically generates negative pulses to drive TRIACs, making it suitable for two-wire AC applications.
