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.  
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.  
Its PIR sensor detects infrared power variations induced  
by the motion of a human body and transforms it to a
