PT8A2645 - PIR Sensor Light Switch

Download the PT8A2645 datasheet PDF (PT8A2641 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for pir sensor light switch.

Description

The PT8A264X is a CMOS LSI chip designed for use in automatic PIR lamp control.

It can operate with a 2-wire configuration for triac applications or with a 3-wire configuration for relay applications.

Features

  • Operating voltage: 5V (Typ. ).
  • Average supply current: 120µA (Typ. ).
  • 2 stage op-amp for filter.
  • Build-in noise rejection circuit.
  • On-chip regulator.
  • Adjustable output duration.
  • Override function.
  • ON/AUTO/OFF selectable by MODE pin.
  • Apply to AC 220V/50Hz and 110V/60Hz.
  • Auto-reset if the ZC signal disappears over 3 seconds.
  • Output pulse (PT8A2641/5/7) to drive triac or output level (PT8A2642/6/8) to drive relay.
  • CDS to enable/disabl.
