PT8A2641 - PIR Sensor Light Switch

General 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.

Key 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.
