Datasheet Constant Current LED Drivers 50V 500mA 1ch Source Driver for Automotive BD83732HFP-M /BD83733HFP-M General Description BD83732HFP-M and BD83733HFP-M are 50V tolerant LED current drivers. Suitable for Automotive LED applications, it can control light through constant current output with control using PWM. Having LED open/short detective circuit and LED current de-rating functions integrated, it can deliver high reliability. By utilizing Rohm’s patented PBUS function, it is possible to turn OFF all LEDs when a row of LEDs are short/open-circuited if multiple number of the ICs are used In case the LED connected to the output IOUT terminal has 2 LEDs in serise, BD83732HFP-M has to be used, in case of 3 LEDs in series - BD83733HFP-M ( Refer to Page.
