General Description
The HT7712B/HT7713B is a CMOS fabricated
LSI chip in an 8-lead DIP package. It is de-
signed 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 per-
formance. The touch sensitive input can sustain
very heavy capacitive loading and propagate

sense through a highly resistive line. The appli-
cation circuit of the HT7712B/HT7713B is very
simple.
Of these two chips, the HT7713B is a 3-step
dimmer controller whose trigger angles are set
at 17°, 86°, 121° — where 17° is the brightest,
86° the medium brightness, and 121° the dark-
est. The HT7712B, on the other hand, is an
ON/OFF switch whose ON state is set at an
angle of 17°.
