Top 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, coldcrank, 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 resistors
- Internal or external PWM dimming
- Controlled output drivers slew during PWM for lower EMI
- Fault detection features: LED string open, LED pin short-to-ground, single LED short, VOUT short-toground, VIN overvoltage, and thermal protection
- Input supply and temperature-based derating
- Automotive K-temperature range (–40°C to 150°C)
