Overview
The BCR401UW6-7 is a linear LED constant current regulator manufactured by Diodes Incorporated. It provides a fixed output current of 100 mA with an input voltage range from 1.4 V to 40 V. The device supports PWM dimming and operates within a junction temperature range of -55°C to +150°C. It is housed in a SOT-26-6 surface-mount package and meets AEC-Q100 automotive qualification standards.
Feature Summary
- Provides stable constant current regulation for single-channel LED applications
- Supports external PWM dimming control for brightness adjustment
- Operates across an extended industrial and automotive temperature range
Applications
- Automotive interior lighting systems
- General solid-state lighting fixtures
- LED signage and indicator circuits
Procurement Notes
Verify the specific suffix 'Q' indicates AEC-Q100 automotive qualification status as per manufacturer documentation. Confirm the SOT-26-6 package type matches the target PCB footprint. Ensure the input voltage supply remains within the 1.4 V to 40 V operational limits to prevent device damage or malfunction during procurement validation.
Selection Notes
Select this component when a fixed 100 mA drive current is required for high-voltage LED strings. The linear topology simplifies design by eliminating external inductors. Consider the thermal dissipation capabilities given the 1.19 W power rating. Verify compatibility with the intended PWM dimming frequency specifications before finalizing the circuit design.
Part Context
This part belongs to the BCR series of LED drivers from Diodes Incorporated, designed for reliable operation in demanding environments. The series includes variants with different current ratings and dimming capabilities. The BCR401UW6-7 specifically targets applications requiring robust automotive-grade performance with simplified linear regulation architecture.
Replacement Considerations
Check for BCR401UW6Q-7 which shares similar electrical characteristics but may have distinct packaging or qualification nuances. Verify pinout compatibility with existing designs before substituting.
