Linear LED driver for automotive lighting
The Infineon BCR402WH6327XTSA1 is a linear LED driver designed for constant-current operation in automotive lighting applications. It delivers a regulated 60 mA output current from a supply range of 1.2 V to 18 V, making it suitable for driving single or multiple LEDs in series within the voltage budget. The internal switch is integrated, so no external pass transistor is needed. AEC-Q101 qualification confirms it meets the stress and lifetime requirements for under-hood and cabin lighting modules.
Package and footprint for space-constrained boards
Housed in an SC-82A / SOT-343 package (Infineon code PG-SOT343-3D), this part is a compact surface-mount device suited for LED modules where board area is tight. The three-pin footprint simplifies layout — the supply, output, and ground connections are straightforward. No exposed thermal pad, so thermal management relies on the PCB copper and ambient airflow; keep the junction temperature within the rated limits by derating the output current at high ambient temperatures.
