Overview
The BD8374HFP-MTR is a single-channel automotive LED source driver IC from ROHM Semiconductor, designed for high-reliability applications. It supports a maximum output current of 500mA per channel and operates within an input voltage range of 4.5V to 42V. The device features PWM dimming capability with an integrated CR timer for frequency control. It is housed in an HRP-7 package and qualified under AEC-Q100 standards for automotive use. The operating temperature range spans from -40°C to +125°C, ensuring stability in harsh environments.
Feature Summary
- Integrated constant-current source topology optimized for automotive LED driving
- Built-in protection circuits including LED open/short detection and overvoltage mute
- PWM dimming function with integrated timing components for simplified design
- Abnormal output detection (PBUS) enabling unified control across multiple channels
Applications
- Automotive exterior lighting systems requiring high-voltage tolerance
- Interior ambient LED illumination modules
- Multi-column LED arrays with centralized fault management
- High-reliability automotive lighting control units
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and revision status. Note that a Product Change Notice (PCN) is scheduled for this product; while electrical characteristics remain unchanged, certain specifications may be updated. Confirm functional safety classification and RoHS compliance directly with the supplier prior to finalizing procurement orders.
Selection Notes
Select this component when a single-channel, high-voltage tolerant LED driver is required for automotive environments. The integrated PBUS feature makes it suitable for systems where multiple drivers manage separate LED columns but require synchronized shutdown during faults. Ensure the application input voltage stays within the 4.5V to 42V range and that thermal dissipation aligns with the HRP-7 package capabilities.
Part Context
This part belongs to the BD8374 series of automotive LED source drivers. It shares functional similarities with other members like the BD8374EFJ-M but differs in package type and pinout configuration. The series is characterized by its robust protection mechanisms and compatibility with standard automotive power supply networks, targeting OEM and aftermarket lighting solutions.
Replacement Considerations
No direct public substitute part numbers are documented for this specific model. Consider evaluating other members of the BD8374 series or similar ROHM automotive LED drivers if pin compatibility allows, though cross-model substitution requires careful verification of package dimensions and electrical parameters.
