A6274 Linear Current Regulator/Controller

The A6274 and A6284 are programmable linear current regulator ICs for driving automotive LED arrays. The LED current is programmed by external resistors. These devices sink up to 60 mA (A6274) or 120 mA (A6284), from each of six LED pins, to drive strings of high-brightness LEDs. LED pins can be par.

A6274 Features

* Six LED current sinks rated up to 60 mA (A6274) or 120 mA (A6284)

* Total LED drive current

* up to 360 mA or 720 mA

* Wide input voltage range of 5 to 42 V for start/stop, cold- crank, and load-dump requirements

* Low-dropout voltage

* drives two series
