Constant Current LED Drivers

50V 500mA

1ch Source Driver for Automotive

BD8374HFP-M BD8374EFJ-M

General Description

Key Specifications

BD8374HFP-M and BD8374EFJ-M are 50V-withstanding

LED source drivers. Most suitably for Automotive

LED driving, it can control light through PWM of constant

current output.

 Input Voltage Range: 4.5V to 42V

 Max Output Current: 500mA (Max)

 Output Current Accuracy: ±5% (Max)

 Operating Temperature Range: -40°C to +125°C

Having LED open/short detective circuit and overvoltage

mute functions integrated, it can deliver high reliability.

Also by utilizing our patented PBUS function, it is possible

to turn OFF all LEDs in case where a row of LEDs are

short/open-circuited if multiple rows of LEDs are driven

through multiple number of the ICs.
