HT7713B Datasheet (Holtek Semiconductor)

HT7713B, Touch Dimmer

The HT7712B/HT7713B is a CMOS fabricated LSI chip in an 8-lead DIP package.

It is designed to control the brightness of lamps by changing the firing angles of the TRIAC through a touch sensitive input.

The chip can be used either as a 3-step or a switch function dimmer.
