BD83740HFP-M
50V 500mA 1ch Source Driver for Automotive

BD83740HFP-M is 50V-withstanding LED source drivers. Most suitably for Automotive LED driving, it can control light through PWM of constant current output. Having LED open detective function and overvoltage mute function 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 opened if multiple rows of LEDs are driven through multiple number of the ICs.
