Datasheet Summary
A6274, A6274-1 A6284, A6284-1
Linear Current Regulator and Controller for Automotive LED Arrays
Features
AND BENEFITS
- 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 bined in two groups with separate ENx and
ISETx
- LED current level set by external reference resistors
- Internal or external PWM dimming
- Controlled output drivers slew during PWM for lower
- Fault detection Features
