BCR402U
Overview
Linear LED driver IC for low power LEDs
The BCR402U 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 20mA
- Output current adjustable by resistor up to 65mA
- Supply voltage up to 40V
- High side current control, PNP transistor power stage
- PWM dimmable by external transistor
- Up to 750mW power dissipation in a small SC74 package
- Negative thermal coefficient reduces output current at higher temperatures
- Automotive qualified according to AEC Q101
- BCR402U E6433 is available as a 10k reel
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
