Overview
The BD8379EFV-ME2 is a 12-channel LED driver IC from ROHM Semiconductor, designed for automotive applications. It features a 3-wire serial interface and operates within an input voltage range of 3 V to 5.5 V. Each channel provides up to 50 mA output current, with a maximum total output current of 600 mA. The device supports a maximum output voltage of 35 V and functions at switching frequencies up to 1.25 MHz. It is qualified under AEC-Q100 standards and operates between -40°C and +105°C in an HTSSOP-B20 package.
Feature Summary
- Integrates internal 12-channel power transistors with open-drain outputs for direct LED control.
- Supports cascade connections and includes low EMC noise optimization via controlled output slew rates.
- Features functional safety supportive design compliant with AEC-Q100 Grade 1 automotive standards.
Applications
- Automotive interior lighting systems
- Ambient lighting control modules
- Dashboard indicator arrays
Procurement Notes
Verify the specific suffix ME2 against the official datasheet to confirm pinout and thermal characteristics. Ensure the ordering part number matches the required tape-and-reel quantity of 2500 units. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when a compact solution for multiple low-current LEDs is required in space-constrained automotive environments. The 3-wire serial interface reduces microcontroller pin usage compared to parallel control methods. Consider the 35 V耐压 rating for compatibility with standard vehicle electrical architectures.
Part Context
This device belongs to ROHM's automotive-grade LED driver family, specifically engineered for high reliability in harsh environments. It complements other series like the BD83816 by offering a 12-channel configuration in a smaller HTSSOP-B20 footprint, targeting cost-sensitive yet safety-critical lighting applications.
Replacement Considerations
The BD8379EFV-M is listed as an alias; verify if the ME2 suffix denotes a specific packaging or environmental qualification change. No other direct cross-model substitutes are confirmed in the provided data.
