BD83732HFP-M Datasheet | ROHM

Constant Current LED Drivers 50V 500m A 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.18 LED Open Detection / Disable LED Open Detection ). Features - AEC-Q100 Qualified - Variable form Constant-Current Source Driver - PWM Dimming Function - LED constant current set by external resistor - LED Current De-rating Function - LED Open/Short detection - Disable LED Open Detection at low power supply - Temperature Protective - Abnormal Output Detection and Output Functions (PBUS) Key Specifications - Input Voltage Range: 4.5V to 42V - Max Output Current: 500m A (Max) - Output Current Accuracy: ±5% (Max) - Operating Temperature Range: -40°C to +125°C Packages HRP7 W(Typ) x D(Typ) x H(Max) 9.395mm x 10.540mm x 2.005mm HRP7 Application - On-board Exterior Lamp (Rear Lamp, Turn Lamp, DRL/Position Lamp, Fog Lamp, etc.) - On-board Interior Lamp (Air Conditioner Lamp, Interior Lamp, Cluster Light,...
