Control IC for headlights

  • 14-Jan-2011 01:16 EST

Renesas Electronics’ control IC for automotive LED headlights provides an integrated current-control function for constant-current drive of up to 12 power LEDs connected in series and a predriver function for driving external metal-oxide-semiconductor field-effect transistors (MOSFETs). The μPD168891 IC also features integrated protection functions including LED current and external MOSFET overcurrent protection in a compact package with low thermal resistance. The unit can be combined with other devices such as MOSFETs, Schottky diodes, and choke coils to build electronic control units for LED headlights.
