40 V 600 mA 1ch Constant Current Driver

for Automotive LED Lamps

BD18336NUF-M

General Description

Key Specifications

The BD18336NUF-M is a constant current driver IC for

driving automotive LED lamp, that can withstand up to 40

V. Small-size package is suitable for use in socket LED

driver applications.

The BD18336NUF-M offers high reliability with built-in

functions for the thermal de-rating function, the LED open

detection, the output short circuit protection, the SET pin

short circuit protection, the over-voltage mute function, the

current bypass function at reduced-voltage, the output for

fault flag function and the input for output current OFF

control signal.
