BCR405UW6Q 50 to 100mA LED CONSTANT CURRENT REGULATOR in SOT26 Description Features This Linear LED driver is designed to meet the stringent requirements LED Constant Current Regulator Using PNP Emitter- of automotive applications. Follower with Emitter Resistor to Current Limit I = 50mA 10% Constant Current (Preset) OUT I up to 100mA Adjustable with an External Resistor OUT The BCR405UW6Q monolithically integrates a transistor, diodes, and V 40V Supply Voltage S resistors to function as a Constant Current Regulator (CCR) for LED P up to 1W in SOT26 D driving. The device regulates with a preset 50mA nominal that can be LED Dimming Using PWM up to 25kHz adjusted with external resistor up to 100mA. It is designed for driving Negative Temperature Coefficient (NTC) Reduces I with OUT LEDs in strings and will reduce current at increasing temperatures to Increasing Temperature self-protect. Operating as a series linear CCR for LED string current Parallel Devices to Increase Regulated Current control, it can be used in applications with supply voltages up to 40V. Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) With no need for additional external components, this CCR is fully The BCR405UW6Q is suitable for automotive applications integrated into an SOT26, minimizing PCB area and component count. requiring specific change control this part is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities.
