BCR421UW6Q-7 Description

Short technical summary and product information.

The BCR421UW6Q-7 from Diodes Incorporated is a linear LED constant current regulator (CCR) designed to meet stringent automotive application requirements. This device integrates transistors, diodes, and resistors to provide reliable linear LED driving. It features a preset nominal output current of 10mA, which can be adjusted externally up to 350mA. The regulator operates with a maximum supply voltage of 40V and includes a low-side control Enable (EN) pin, allowing for LED dimming via pulse-width modulation (PWM) up to 10 kHz.

 

Designed for driving LEDs in strings, the BCR421UW6Q-7 incorporates a negative temperature coefficient (NTC) that reduces output current as temperature increases, providing self-protection. Its fully integrated design in an SOT-26 package minimizes PCB area and component count. Applications include automotive interior lighting and mood/decorative lighting.

 

Key features include AEC-Q101 qualification for high reliability, totally lead-free and RoHS compliant construction, and a "Green" device designation. The device is supplied in a SOT-26 (SC-74) molded plastic case suitable for surface mounting.
