BCR405UW6Q-7

BCR405UW6Q 50 to 100mA LED CONSTANT CURRENT REGULATOR in SOT26 Description Features This Linear LED driver is designed to meet the stringent requirements of automotive applications. • The BCR405UW6Q monolithically integrates a transistor, diodes, and resistors to function as a Constant Current Regulator (CCR) for LED driving. The device regulates with a preset 50mA nominal that can be adjusted with 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. • • • • LED Constant Current Regulator Using PNP EmitterFollower with Emitter Resistor to Current Limit IOUT = 50mA ± 10% Constant Current (Preset) IOUT up to 100mA Adjustable with an External Resistor VS – 40V Supply Voltage PD up to 1W in SOT26 • • LED Dimming Using PWM up to 25kHz Negative Temperature Coefficient (NTC) Reduces IOUT with 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 BCR405UW6Q is suitable for automotive applications requiring specific change control; this part is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/ With no need for additional external components, this CCR is fully integrated into an SOT26, minimizing PCB area and component count. • • • • Applications Mechanical Data Constant current regulation (CCR) in automotive LED lighting: • • • • • • Interior and Exterior Automotive LED Lighting Dome and Mood Lighting Puddle Lighting Side Marker Lights • • • Case: SOT26 Case Material: Molded Plastic. “Green” Molding Compound.
