BA6951FS-E2

Overview

The BA6951FS-E2 is a reversible motor driver designed for brush DC motors, manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 6 V and supports an output current of up to 800 mA. The device features a low operating supply current of 6 mA and handles a power dissipation of 813 mW. It functions across a temperature range from -20°C to +75°C. The component is housed in a 16-pin SSOP-A-16 package suitable for surface mount technology.

Feature Summary

• Directly drives brush DC motors requiring forward and reverse rotation
• Integrates control and power stages for simplified circuit design
• Supports parallel interface for bidirectional motor control

Applications

• Brush DC motor control in consumer electronics
• Bidirectional fan or pump drive systems
• Small appliance motor regulation

Procurement Notes

Verify the specific suffix E2 for RoHS compliance status against official documentation. Confirm the SSOP-16 package variant matches the target PCB footprint. Check current lifecycle status as some sources indicate end-of-life conditions. Ensure the 3V-6V operating range aligns with the system power supply constraints before integration.

Selection Notes

Select this component when a compact solution for low-voltage brush motor direction control is required. The integrated power stage reduces external component count compared to discrete H-bridge designs. Verify that the 800 mA output capability meets the peak load requirements of the connected motor. Consider the thermal performance given the 813 mW dissipation limit in the SSOP package.
