Overview
The BD7931F-E2 is a single reversible motor driver manufactured by ROHM Semiconductor, designed for low-current applications up to 0.5A. It operates within a supply voltage range of 4.5V to 14V and features an SOP-8 surface-mount package. The device supports bidirectional control with a maximum power dissipation of 690mW and functions reliably across temperatures from -40°C to +85°C.
Feature Summary
- Supports reversible operation for single motor control
- Integrated protection against thermal issues
- Compatible with standard logic level inputs
Applications
- Small DC motor speed control in home appliances
- Fan rotation direction management in ventilation systems
- Automotive accessory motor drivers
Procurement Notes
Verify the exact suffix E2 for RoHS compliance and lead-free status. Confirm the SOP-8 package variant matches your PCB footprint requirements. Check current stock levels as availability may fluctuate due to production cycles. Ensure input voltage ratings align with your system's power supply specifications before ordering.
Selection Notes
Select this component when driving small DC motors requiring bidirectional control under 0.5A. It is suitable for battery-powered or low-voltage AC/DC converted systems. Consider its thermal performance if operating near the upper temperature limits. Compare with other ROHM motor drivers if higher current capacity or different packaging is needed.
Part Context
This part belongs to ROHM's line of PMIC motor controllers. It serves as a dedicated solution for simple reversible motor tasks. The series focuses on cost-effective integration for consumer electronics. It replaces older discrete solutions by combining drive and protection in one IC.
Replacement Considerations
Check for direct pin-compatible alternatives within the same ROHM family. Verify that substitute parts support the same 4.5V-14V input range. Ensure replacement ICs offer equivalent 0.5A output current capability. Confirm thermal resistance values match your heat dissipation design.
