HT7712B/HT7713B Touch Dimmer Features • • • • High noise immunity CMOS technology Operating voltage: 10V Line frequency: 60Hz or 50Hz.
High sensitivity and stability • • • Polarity insensitive with AC line Loading range of sense input from 0 to 1200pf Minimum peripheral components General Description 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.
The high sensitivity and stability of the HT7712B/HT7713B ensure its high performance.
The touch sensitive input can sustai...
