BA6208F

Full Half-Bridge (H Bridge) Drivers Overview

The BA6208F is a monolithic integrated circuit designed for driving reversible DC motors. It integrates a logic control section and an output power stage capable of delivering up to 100mA typical output current. The device supports direct TTL-level logic input for forward, reverse, and forced stop operations. Key electrical parameters include a recommended operating supply voltage range of 4.5V to 15.0V. The IC features built-in power transistors and surge absorption diodes to protect against inductive kickback. Standby current consumption is minimized when inputs are low, making it suitable for battery-powered applications.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix (e.g., -E2) against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the application voltage remains within the 4.5V to 15.0V range to prevent device damage. Confirm that the load current does not exceed the 100mA typical rating without adequate thermal management. Check for any obsolete status notifications from Rohm Semiconductor before finalizing procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for simple reversible motor control requiring minimal external components. It is appropriate for low-power applications where direct TTL interfacing is necessary. Consider thermal dissipation if continuous operation near the maximum current limit is required. Compare with higher-current alternatives if the load exceeds typical specifications. Ensure the supply voltage compatibility matches the system design constraints.

Full Half-Bridge (H Bridge) Drivers Part Context

The BA6208F belongs to Rohm's family of single-chip motor driver ICs. It simplifies motor control designs by combining logic and power stages in one package. This integration reduces board space and component count compared to discrete solutions. The device is commonly used in legacy and cost-sensitive consumer electronics where reliable reversible motor operation is required.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Compatible substitutes include BA6285FS and BA6951FS from Rohm, which offer similar reversible motor driver functionality. Cross-reference pinouts and current ratings carefully. Other manufacturers may offer equivalent parts like AZ6208B, but verify electrical characteristics and interface compatibility before substitution.
