General Description
The PT8A261 and PT8A262 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.
Applications
Energy saving auto-switch in Garden, kitchen,
bathroom, corridor, storage or yard
Auto light in meeting room
