Constant Current LED Drivers
50V 500mA
1ch Source Driver for Automotive
BD8374HFP-M BD8374EFJ-M
General Description
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.
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.
Key Specifications
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
