Infineon Technologies AG Linear LED Driver IC BCR420U

Linear LED driver IC for low/medium power LEDs

The BCR420U linear LED driver IC is tailored to drive low and mid power LEDs in general and automotive lighting applications.

Summary of Features

• LED drive current preset to 10mA
• Output current adjustable by resistor up to 150mA
• Supply voltage up to 40V
• Low side current control, NPN transistor power stage
• PWM dimmable by external transistor
• Up to 1000mW 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

Applications

• 24 GHz radar system
• Automotive body control module (BCM)
• Automotive LED lighting systems
• Connected and smart lighting for IoT
• Domain controller for ADAS and autonomous driving
