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.

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 WLEDs from 7 V input.
Gate driver for external ballast P-MOSFET.
LEDs combined in two groups with separate ENx and ISETx.
LED current level set by external reference resist.
