LS7232ND Datasheet (LSI Computer Systems) - TOUCH CONTROL LAMP DIMMER

LS7232ND, TOUCH CONTROL LAMP DIMMER

LS7232ND is a MOS integrated circuit designed to control brightness of incandescent lamps.

The output of this IC controls the brightness of a lamp by controlling the firing angle of a triac connected in series with the lamp.

All internal timings are synchronized with the line frequency by means of

LS7232ND Features

* Phase-lock loop synchronization allows use in Wall Switch applications.

* Provides brightness control of incandescent lamps with touch plates or pushbutton switches.

* Controls the duty cycle from 23% to 88% (conduction angles for AC half-cycles between 41˚ and 158˚, respe
