A6274-1
Description
The A6274 and A6284 are programmable linear current regulator ICs for driving automotive LED arrays.
Key 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
- Low-dropout voltage—drives two series WLEDs from
- Gate driver for external ballast P-MOSFET
- LEDs bined in two groups with separate ENx and
- LED current level set by external reference resistors
- Internal or external PWM dimming
- Controlled output drivers slew during PWM for lower
- Fault detection features: LED string open, LED pin
Applications
- Automotive rear bination light
