Overview
The BD18353MUF-ME2 is a single-channel automotive-grade LED lighting driver IC manufactured by ROHM Semiconductor. It utilizes a boost topology to drive LEDs with an input voltage range of 5 V to 65 V and supports output voltages up to 65 V. The device operates at a switching frequency between 200 kHz and 2.5 MHz. It features PWM dimming capabilities and includes built-in short circuit and thermal protection mechanisms. Qualified under AEC-Q100 standards, it functions within a temperature range of -40°C to +125°C and is housed in a VQFN20QV3535 package.
Feature Summary
- Supports PWM dimming via internal generation circuitry for flexible duty cycle control.
- Integrates high-side current detection amplifier for precise monitoring.
- Provides fault status output through the FAULT_B terminal for abnormal state detection.
- Includes dual-system analog dimming and a high-precision 3.0 V reference power supply.
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- High-current LED controller circuits
Procurement Notes
Verify the specific suffix ME2 against the official datasheet to confirm RoHS compliance and automotive qualification status. Ensure the ordering part number matches the required VQFN20QV3535 package variant. Confirm that the application design accounts for the specified operating temperature range and switching frequency constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-channel boost driver with integrated PWM dimming and high-voltage support. It is suitable for applications needing AEC-Q100 qualification and robust protection features like thermal and short-circuit safeguards. Consider the VQFN20QV3535 package size and wettable flank installation requirements during PCB layout.
Part Context
This part belongs to the BD18353 series of one-channel large-current LED controllers designed for automotive use. It is distinct from other variants such as the BD18353EFV-ME2, which uses a different HTSSOP-B-20 package. The MUF-ME2 designation specifically indicates the VQFN package type and updated manufacturing specifications.
Replacement Considerations
The BD18353MUF-M is listed as an alias for this part number. Verify functional equivalence and package compatibility if substituting with non-suffix versions or other channel counts within the same family.
