General Description
The HT761X is a CMOS LSI chip designed for
use in automatic PIR lamp control. It can oper-
ate with a 2-wire configuration for triac applica-
tions or with a 3-wire configuration for relay
applications. The chip is equipped with opera-
tional amplifiers, a comparator, timer, a zero
crossing detector, control circuit, a voltage regu-
lator, a system oscillator, and an output timing
oscillator.
Its PIR sensor detects infrared power vari-
ations 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 is turned on with an adjustable duration.
The HT761X offers three operating modes (ON,
AUTO, OFF) which can be set through the
MODE pin. While the chip is working in the
AUTO mode the user can override it and switch
to the TEST mode, or manual ON mode, or
return to the AUTO mode by switching the
power switch. The chip is enclosed in a 16 pin
DIP/SOP.
Applications
PIR light controllers
Motion detectors
Alarm systems
Auto door bells
