BCR402UW6Q

20 TO 100mA LED CONSTANT CURRENT REGULATOR IN SOT26

Description

Features

This Linear LED driver is designed to meet the stringent requirements

of automotive applications.



LED Constant Current Regulator Using PNP Emitter-Follower

with Emitter Resistor to Current Limit



I_OUT= 20mA ± 10% Constant Current (Preset)

I_OUTup to 100mA Adjustable with an External Resistor

V_S– 40V Supply Voltage

The BCR402UW6Q monolithically integrates a transistor, diodes, and

resistors to function as a Constant Current Regulator (CCR) for LED

driving. The device regulates with a preset 20mA nominal that can be

adjusted with an external resistor up to 100mA. It is designed for

driving LEDs in strings and will reduce current at increasing

temperatures to self-protect. Operating as a series linear CCR for

LED string current control, it can be used in applications with supply

voltages up to 40V.

P_Dup to 1W in SOT26

LED Dimming Using PWM up to 25kHz

Negative Temperature Coefficient (NTC) Reduces I_OUTwith

Increasing Temperature



Parallel Devices to Increase Regulated Current

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

The BCR402UW6Q is suitable for automotive applications

requiring specific change control; this part is AEC-Q101

qualified, PPAP capable, and manufactured in IATF 16949

certified facilities.

With no need for additional external components, this CCR is fully

integrated into the SOT26, minimizing PCB area and component

count.
