PIR Sensor Light Switch Controller
Features
General Description
The PT8A2611 and PT8A2621 are low power mixed
signal CMOS LSI designed for the automatic lamp
control using PIR sensor as motion detector.
With on chip noise filter and voltage regulator, the IC
provides stable operations throughout temperature
range. CDS input to disable day time operation is
desired.
2-stage operational amplifier as filter
Built-in noise rejection circuit
On-chip regulator
Override function (PT8A2621 only)
Synchronous with AC 220V/50Hz and 110V/60Hz
Pulse output (PT8A2611) for TRIAC drive or
level output (PT8A2621) for relay drive
CDS to enable/disable output
Adjustable output on time duration
ON/AUTO/OFF selectable by MODE pin
Auto-reset if the ZC signal disappears over 3 seconds
40 seconds warm-up
Quick check mode for initial installation
Operating voltage: 5V
Stand-by current: 80µA
Package:16-pin DIP and 16-pin SOP
