General Description
The PT8A2612 is a CMOS LSI chip based on 260
base designed for use in automatic PIR lamp control.
It can operate with a 2-wire configuration for triac
applications with dimmer function or 3-wire
configuration for RELAY application.
Its PIR sensor detects infrared power variations
induced by the motion of a human body and
transforms it to a voltage variation. If the PIR output
voltage variation conforms to the criteria (refer to the
functional description), the lamp can softly turn on
as the below order, 25% lighteness, 50%, 75% 100%
as well as turn off as reverse order with an adjustable
duration.
The PT8A2612 offers three operating modes (TEST,
AUTO, disable dimmer) which can be set through
the MODE pin. While the chip is working in the AUTO
mode the user can override it and switches to the
quickly check mode, or manual ON mode, or return
to the AUTO mode by switching the power switch.
Applications
Energy saving auto-switch in Garden, kitchen,
bathroom, corridor, storage, and yard
Auto light in Meeting-room
