BCR421UW6Q
Description
These linear LED drivers are designed to meet the stringent requirements of automotive applications. The BCR420UW6Q and BCR421UW6Q monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving.
Key Features
- LED Constant Current Regulator using NPN Emitter-Follower with Emitter Resistor to Current Limit
- IOUT - 10mA ± 10% Constant Current (Preset)
- IOUT up to 350mA Adjustable with an External Resistor (BCR421UW6Q)
- VOUT - 40V Supply Voltage
- PD up to 1W in SOT26
- Low-Side Control Enabling PWM Input < 25kHz (BCR421UW6Q)
- Negative Temperature Coefficient (NTC) Reduces IOUT with Increasing Temperature
- Parallel Devices to Increase Regulated Current
