Overview
The BD18340FV-ME2 is a single-channel LED lighting driver IC designed for automotive applications, certified to AEC-Q100 standards. It operates within an input voltage range of 4.5 V to 19 V and delivers a maximum output current of 400 mA. The device supports both Boost and Buck topologies with adjustable output voltage. It functions at switching frequencies between 100 Hz and 5 kHz and includes PWM dimming capabilities. The component is housed in an SSOP-B-16 package and withstands operating temperatures from -40°C to +125°C.
Feature Summary
- Supports Boost and Buck converter topologies for flexible LED string configurations
- Integrates constant current control with PWM dimming functionality
- Includes protection mechanisms such as over-voltage mute and short-circuit protection
Applications
- Automotive exterior lighting systems
- LED headlamp circuits
- Tail lamp assemblies
Procurement Notes
Verify the specific suffix (e.g., ME2) against the required datasheet revision and packaging configuration. Confirm that the SSOP-B-16 package dimensions align with the target PCB footprint. Ensure the selected variant meets the necessary AEC-Q100 Grade requirements for the intended automotive environment. Cross-reference the part number alias BD18340FV-M if sourcing from legacy inventories.
Selection Notes
Select this component when designing single-channel LED drivers requiring both buck and boost flexibility within a 4.5 V to 19 V supply range. It is suitable for applications needing precise constant current regulation up to 400 mA. Consider its thermal performance in the SSOP-B-16 package for high-temperature automotive environments. Verify compatibility with the required PWM dimming frequency range of 100 Hz to 5 kHz.
Part Context
This part belongs to ROHM's automotive-grade LED driver portfolio, specifically engineered for reliability in vehicle lighting. It complements other BD183xx series components by offering a versatile single-channel solution. The inclusion of AEC-Q100 qualification ensures it meets stringent automotive quality and durability standards compared to general-purpose industrial drivers.
Replacement Considerations
BD18340FV-ME2 is the primary ordering designation for the BD18340FV-M core function. No direct cross-manufacturer substitutes are documented in the provided data.
