General Description

The A6274 and A6284 are programmable linear current regulator ICs for driving automotive LED arrays.

The LED current is programmed by external resistors.

These devices sink up to 60 mA (A6274) or 120 mA (A6284), from each of six LED pins, to drive strings of high-brightness LEDs.

Overview

A6274, A6274-1 A6284, A6284-1 Linear Current Regulator and Controller for Automotive LED.

Key Features

  • Six LED current sinks rated up to 60 mA (A6274) or 120 mA (A6284).
