Overview
The BD63003MUV-E2 is a three-phase brushless DC motor pre-driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10.8 V to 26.4 V, with a typical operating voltage of 24 V and quiescent current of 4.5 mA. The device supports switching frequencies between 10 kHz and 50 kHz. It is housed in a VQFN-32 package (VQFN032V5050) and functions over an extended temperature range from -40°C to +85°C. Designed for MOS transistor interfaces, it serves as a driver for brushless motors requiring external power stages.
Feature Summary
- Provides pre-driver functionality for three-phase brushless DC motors
- Supports interface with external MOS transistors for power driving
- Operates with standard logic level inputs for control signals
Applications
- Fan motor control systems
- Optical disk drive (ODD) spindle motors
- Paper feed mechanisms in printers and copiers
- Multi-prism scanning devices
Procurement Notes
Verify the specific suffix E2 indicates RoHS compliance when sourcing. Confirm the VQFN-32 package marking matches the datasheet silkscreen. Ensure the application circuit includes appropriate external MOSFETs as this component is a pre-driver only. Check for alternate revisions if long-term availability is required.
Selection Notes
Select this part when a dedicated pre-driver for BLDC motors is needed rather than an integrated power stage. It is suitable for designs utilizing external high-side and low-side MOSFETs. Consider the 24 V nominal supply requirement and the VQFN thermal performance for the specific PCB layout constraints.
Part Context
This component belongs to ROHM's series of three-phase brushless motor drivers. It is part of a family that includes variants like the BD63006MUV-E2, which integrates power MOSFETs. The BD63003MUV-E2 specifically focuses on the pre-driver role, allowing designers to select custom power switches based on current and voltage requirements.
Replacement Considerations
The BD63003MUV is listed as an alias or predecessor variant. For integrated solutions, the BD63006MUV-E2 offers similar control features but with built-in power MOSFETs. Verify pin compatibility and thermal dissipation differences when substituting.
