Overview
The BD8372HFP-MTR is a linear LED driver IC designed for automotive applications, featuring a single constant current output capable of delivering up to 200mA. It operates within an input voltage range of 5.5V to 40V and supports a maximum output voltage of 50V. The device utilizes an HRP-7 package with dimensions of 9.395x10.54mm and a height of 2.005mm. It is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Supports H/L current setting via switch control for variable brightness levels
- Integrates protection circuits including LED open/short detection and overvoltage mute
- Features PBUS function for unified OFF control during abnormal output conditions
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- Tail light assemblies
Procurement Notes
Verify the specific suffix MTR indicates tape and reel packaging when placing orders. Confirm that the component meets AEC-Q100 qualification requirements for your target automotive application. Ensure the design accommodates the thermal characteristics associated with the HRP-7 package size and surface mount installation type.
Selection Notes
Select this model for applications requiring precise linear regulation of LED current with integrated fault protection. It is suitable for designs needing high-voltage tolerance up to 50V on the output side. Consider the HRP-7 footprint constraints and the requirement for external switching components if implementing the H/L current setting feature.
Part Context
This component belongs to the BD8372 series of high-voltage LED source drivers developed by ROHM Semiconductor. The series is engineered specifically for automotive environments, offering robust protection features against common failure modes such as open circuits and short circuits in LED strings.
Replacement Considerations
The BD8372EFJ-ME2 serves as a pin-compatible alternative in an HTSOP-J-8 package. Verify package dimensions and thermal dissipation capabilities before substitution.
