PT8A2611 - Pericom Technology

PT8A2611 PIR Sensor Light Switch Controller

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 amplif.
