BD18347EFV-ME2

Overview

The BD18347EFV-ME2 is a four-channel constant current LED driver IC manufactured by ROHM Semiconductor, designed for automotive lighting applications. It features a 40V withstand voltage and supports output currents up to 150mA per channel. The device incorporates an energy sharing control function to optimize power distribution across channels. It operates within a supply voltage range of 4.5V to 19V and includes protection mechanisms such as overvoltage and thermal shutdown. The component is housed in a compact SSOP-B16 package suitable for surface mount technology.

Feature Summary

Four-channel constant current drive capability with integrated energy sharing control
High voltage tolerance rated at 40V for robust automotive operation
Built-in protection circuits including overvoltage and thermal shutdown

Applications

Automotive exterior lighting systems
LED headlamp modules
Fog lamp drivers
Tail light assemblies

Procurement Notes

Verify the specific suffix ME2 against the official ROHM datasheet to confirm pinout and packaging details. Ensure compatibility with automotive grade requirements by checking AEC-Q100 certification status in the manufacturer's documentation. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing multi-channel LED drivers requiring high voltage resilience and efficient energy management. The integrated energy sharing feature makes it suitable for applications where load balancing between channels is critical. Consider the SSOP-B16 package size for space-constrained PCB layouts in automotive environments.

Part Context

This part belongs to the BD183xx series of LED drivers from ROHM, which are optimized for automotive use. The series typically includes variants with different channel counts and voltage ratings. The BD18347EFV-ME2 specifically addresses the need for four-channel control with advanced power management features in a compact form factor.

Replacement Considerations

Consult the official ROHM replacement guide or datasheet revision history for confirmed substitute part numbers. Do not assume cross-compatibility with other series without verifying electrical parameters and pin configurations.
