LS7232NT Datasheet (LSI Computer Systems) - PROXIMITY/TOUCH CONTROL HALOGEN LAMP DIMMER

LS7232NT, PROXIMITY/TOUCH CONTROL HALOGEN LAMP DIMMER

LS7232NT is a CMOS integrated circuit designed for brightness control of incandescent lamps or tranformer coupled low voltage halogen lamps.

The brightness is controlled by controlling the firing angle of a triac in series with the lamp and triggered by the LS7232NT.
