HT7713B 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.
HT7713B Key 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 ponents
- where 17° is the brightest, 86° the medium brightness, and 121° the darkest. The HT7712B, on the other hand, is an ON/OF
- 35.33 -35.33 -35.33 -35.33 30.83
- The IC substrate should be connected to VDD in the PCB layout artwork
