BD18326NUF-M
40V 600mA, 1ch Constant Current Driver for Automotive LED Lamps
The BD18326NUF-M is a constant current driver IC for driving automotive LED lamp, that can withstand up to 40V. Small-size package is suitable for use in socket LED driver applications. The BD18326NUF-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. A Product Change Notice (PCN) is scheduled for this product.
While there will be no changes to electrical characteristics, certain specifications will be updated.
