Overview
The BCR420UFDQ-7 is a linear LED driver IC manufactured by Diodes Incorporated, designed for constant current regulation in lighting applications. It operates within an input voltage range of 1.4 V to 40 V and supports output currents up to 350 mA. The device features a single channel topology and is housed in a U-DFN2020-6 surface-mount package. It is qualified under the AEC-Q100 automotive standard, ensuring reliability in demanding environments. The component functions with a maximum power dissipation of 1.7 W and maintains operation across a wide temperature range from -55 °C to +150 °C.
Feature Summary
- Provides constant current regulation for LED loads without requiring external microcontrollers
- Configurable output current using external resistors
- Automotive-grade qualification compliant with AEC-Q100 standards
Applications
- Automotive interior lighting systems
- General solid-state lighting fixtures
- LED indicator circuits
Procurement Notes
Verify the specific suffix 'Q' indicates AEC-Q100 automotive qualification during procurement. Confirm the U-DFN2020-6 package dimensions match the target PCB footprint. Ensure the selected output current setting via external resistors aligns with the LED string requirements within the 1.4 V to 40 V operating window.
Selection Notes
Select this component when automotive reliability is required for low-voltage LED drivers. The linear topology suits applications where noise immunity is prioritized over efficiency. Compare against non-automotive variants like BCR420UFD-7 if AEC-Q100 certification is unnecessary. Ensure the thermal design accommodates the 1.7 W power dissipation limit in the intended enclosure.
Part Context
This part belongs to the BCR420 series of transistor-based LED drivers from Diodes Incorporated. The series offers configurable current settings for various LED densities. The 'Q' suffix specifically denotes automotive grade compliance, distinguishing it from commercial grade equivalents. It serves as a standalone solution for simple LED control tasks.
Replacement Considerations
BCR420UFD-7 is a commercial grade alternative lacking AEC-Q100 qualification. BCR421UFDQ-7 offers similar automotive qualification but may differ in specific electrical characteristics or pinout configurations. Verify datasheet compatibility before substitution.
