Overview
The BD8372UEFJ-ME2 is a single-channel automotive-grade LED source driver IC manufactured by ROHM Semiconductor. It features a constant current topology with an input voltage range of 5.5 V to 40 V and supports a maximum total output current of 200 mA per channel. The device operates within an extended temperature range from -40°C to +125°C and is housed in an 8-lead HTSOP-J package measuring 4.9 x 6.0 mm. It includes integrated protection circuits for LED open/short detection, overvoltage mute, and thermal shutdown.
Feature Summary
- Supports H/L current setting switch control for variable form constant current source applications
- Integrates LED open and short protection circuits alongside external resistor fault detection
- Includes overvoltage mute and temperature protection functions for enhanced system reliability
- Features abnormal output detection and output functions (PBUS) for multi-LED array monitoring
Applications
- Automotive LED lighting systems requiring high-reliability source drivers
- Multi-row LED arrays where simultaneous shutdown upon fault detection is required
- Applications utilizing H/L current switching for dimming or brightness control
Procurement Notes
Verify the specific suffix ME2 against the manufacturer's latest documentation to confirm pinout compatibility and functional equivalence with legacy variants like the BD8372UEFJ-M. Ensure that the HTSOP-J8 package dimensions align with the target PCB footprint. Confirm RoHS compliance status and automotive qualification requirements prior to finalizing procurement orders.
Selection Notes
Select this component when a single-channel linear LED driver with 200 mA capacity is needed for automotive environments. It is suitable for designs requiring integrated fault protection and H/L current switching capabilities. Consider the 8-HTSOP-J package constraints and the 5.5 V to 40 V input voltage window during circuit design.
Part Context
This part belongs to the BD8372 series of automotive LED source drivers designed for robust performance in vehicle lighting applications. The series emphasizes high reliability through built-in protection mechanisms such as overvoltage mute and thermal shutdown. It serves as a specialized solution for driving LEDs in harsh automotive electrical environments.
Replacement Considerations
The BD8372EFJ-ME2 is a documented variant within the same family. Verify if the EFJ package differs from the UEFJ package in your specific application context before substitution.
