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 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
