Overview
The BD64547MUV-E2 is a system motor driver designed for printer applications, manufactured by ROHM Semiconductor. It integrates bipolar and brushless DC (BLDC) control with four half-bridge outputs. The device supports serial interface communication and delivers an output current of 2 A. Operating within a temperature range of -25°C to +85°C, it consumes 8.5 mA of supply current. The component is housed in a VQFN-48 surface-mount package.
Feature Summary
- Integrates bipolar and BLDC motor control capabilities
- Features four integrated half-bridge driver stages
- Supports serial interface communication protocols
Applications
- Printer motor control systems
- Bipolar stepper motor driving
- Brushless DC motor actuation
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with RoHS directives and material composition requirements. Ensure the ordering part number matches the exact package variant and tape-and-reel specifications required for automated assembly processes. Cross-reference the datasheet revision date to confirm availability of updated electrical characteristics and mechanical drawings.
Selection Notes
Select this component when designing systems requiring integrated control for both bipolar and BLDC motors within a single package. The VQFN-48 form factor suits space-constrained PCB layouts. Verify that the operating voltage and current ratings align with the specific motor load requirements. Confirm compatibility with the host controller's serial interface protocol before finalizing the design.
Part Context
This part belongs to ROHM's PMIC motor driver family, specifically optimized for printer mechanisms. It combines power stage drivers with logic control functions. The series targets high-density integration needs in office automation equipment. The component replaces discrete driver solutions by consolidating multiple bridge stages into one IC.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Consult the manufacturer directly for pin-compatible alternatives or functional upgrades.
