BCR420UW6Q-7

Overview

The BCR420UW6Q-7 is a linear LED constant current regulator manufactured by Diodes Incorporated. It operates with a supply voltage range of 1.4 V to 40 V and delivers an output current up to 350 mA, adjustable via external resistance. The device features a single channel topology in a SOT-26 package. It supports PWM dimming through an external transistor and includes thermal protection that reduces current at elevated temperatures. Certified to AEC-Q101 standards for automotive applications, it functions within a junction temperature range of -55°C to +150°C.

Feature Summary

Integrates NPN emitter follower and resistor for constant current regulation
Supports PWM dimming via low-side control using external transistor
Includes negative temperature coefficient for thermal self-protection
Fully integrated design minimizes PCB area and component count

Applications

Automotive LED lighting systems
LED string current control
General LED driver circuits requiring compact form factor

Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 automotive qualification as per manufacturer documentation. Confirm the '-7' suffix corresponds to the specified reel or cut tape packaging configuration before ordering. Ensure the selected variant matches the required output current adjustment method using external resistors rather than fixed internal settings.

Selection Notes

Select this component when a single-channel linear driver is required for automotive-grade LED applications. It is suitable for designs needing adjustable output currents up to 350 mA with PWM dimming capability. Consider the SOT-26 package constraints and the need for external components for dimming control. Verify input voltage does not exceed the 40 V maximum rating under all operating conditions.

Part Context

This part belongs to the BCR4xxUW6 series of linear LED drivers from Diodes Incorporated. These devices are designed as monolithic solutions integrating transistors, diodes, and resistors. The series offers various current ratings and pin configurations to suit different LED driving requirements while maintaining a small footprint.
