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.

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.

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
