BCR421UW6Q Datasheet Linear Led Constant Current Regulator

Manufacturer: Diodes Incorporated

Overview: BCR420UW6Q / BCR421UW6Q LINEAR LED CONSTANT CURRENT REGULATOR IN.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

These linear LED drivers are designed to meet the stringent requirements of automotive applications.

The BCR420UW6Q and BCR421UW6Q monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving.

The device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA.

Key Features

  • LED Constant Current Regulator using NPN Emitter-Follower with Emitter Resistor to Current Limit.
  • IOUT.
  • 10mA ± 10% Constant Current (Preset).
  • IOUT up to 350mA Adjustable with an External Resistor (BCR421UW6Q).
  • VOUT.
  • 40V Supply Voltage.
  • PD up to 1W in SOT26.
  • Low-Side Control Enabling PWM Input < 25kHz (BCR421UW6Q).
  • Negative Temperature Coefficient (NTC) Reduces IOUT with Increasing Temperature.
  • Parallel Devices to Increase Regulated Curre.
