General Description

The HT761X is a CMOS LSI chip designed for use in au-

tomatic PIR lamp control. It can operate with a 2-wire

configuration for triac applications or with a 3-wire con-

figuration for relay applications. The chip is equipped

with operational amplifiers, a comparator, timer, a zero

crossing detector, control circuit, a voltage regulator, a

system oscillator, and an output timing oscillator.

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 con-

forms 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.
