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 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) PACKAGES: 20-Pin eTSSOP (LP) with Exposed Thermal Pad AEC-Q100 qualified
DESCRIPTION
The A6274 and A6284 are programmable linear current regulator ICs for driving automotive LED arrays. The LED current is programmed by external resistors.
