BCR401U
Overview
Linear LED driver IC for low power LEDs
The BCR401U linear LED driver IC is tailored to drive low power LEDs in general and automotive lighting applications.
Summary of Features
- LED drive current preset to 10 mA
- Output current adjustable by resistor up to 65 mA
- Supply voltage up to 40 V
- High side current control, PNP transistor power stage
- PWM dimmable by external transistor
- Up to 750 mW power dissipation in a small SC74 package
- Negative thermal coefficient reduces output current at higher temperatures
- Automotive qualified according to AEC Q101
Benefits
- Driving current always under control for homogenous light output
- Longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient)
- Easy paralleling of drivers to increase current
- Contributes to longevity and reliability of LED system
Potential Applications
- LED strips, signage and channel letters
- Commercial, architectural and residential lighting
- Shop, ship, train and aircraft lighting
- Automotive interior lighting
