Overview
The BD18395EFV-ME2 is a single-channel automotive-grade LED lighting driver IC manufactured by ROHM Semiconductor. It utilizes a buck topology to regulate current for high-power LEDs, supporting an input voltage range of 4.5 V to 70 V and delivering up to 2 A output current. The device operates within a wide temperature range of -40°C to +125°C and features PWM dimming capabilities with frequencies from 100 Hz to 2 kHz. It is housed in a 20-pin HTSSOP-B package and includes thermal shutdown protection.
Feature Summary
- Integrates a synchronous buck DC/DC converter with an internal switching FET for efficient power regulation.
- Supports both analog and PWM dimming methods for precise brightness control.
- Includes built-in thermal shutdown circuitry to protect against overheating conditions.
Applications
- Automotive exterior lighting systems
- High-power LED headlamp modules
- LED fog lamp drivers
Procurement Notes
Verify the specific suffix ME2 matches the required RoHS compliance and automotive qualification standards. Confirm the HTSSOP-B-20 package dimensions align with PCB layout constraints. Ensure the design accounts for the specified thermal management requirements given the 2A output capability and operating temperature range.
Selection Notes
Select this component when a single-channel, high-current buck driver is required for automotive applications. It is suitable for designs needing a wide input voltage range up to 70V. Consider alternatives if multiple channels or boost topologies are necessary. Verify that the 2A current limit meets the specific LED string requirements.
Part Context
This part belongs to the BD18395 series of LED drivers designed specifically for automotive use. It is AEC-Q100 qualified, ensuring reliability under automotive environmental stresses. The series focuses on providing robust current regulation for high-brightness LED applications in vehicle lighting systems.
Replacement Considerations
Check for direct pin-compatible replacements within the same ROHM family. Verify that any substitute maintains the 70V max input rating and 2A output capacity. Ensure the replacement also holds AEC-Q100 qualification if used in automotive contexts.
