Product Summary
The HT7610B is a CMOS LSI chip designed for use in automatic PIR lamp control. It can operate with a 2-wire configuration for triac applications or with a 3-wire configuration for relay applications. The HT7610B offers three operating modes (ON, AUTO, OFF) which can be set through theMODE pin. 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. The applications of the HT7610B are PIR light controllers, Motion detectors, Alarm systems, Auto door bells.
