Description
The A6274 and A6284 are programmable linear current regulator ICs for driving automotive LED arrays.
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 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.
