BD6221HFP-TR

Full Half-Bridge (H Bridge) Drivers Overview

The BD6221HFP-TR is a half-bridge driver IC manufactured by ROHM Semiconductor, designed for brushed DC motor applications. It operates within a power supply voltage range of 6V to 15V and delivers a maximum output current of 1A per channel. The device features an on-resistance of 1.5 ohms and consumes a typical quiescent current of 2.5 mA. It supports PWM input signals for speed control and includes comprehensive protection circuits against overcurrent, overvoltage, overheating, undervoltage, and short circuits. The component is housed in an HRP7 surface-mount package with seven leads.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with existing design requirements. Confirm that the HRP7 package dimensions match the target PCB footprint. Check for any end-of-life notifications or recommended replacement parts if the component is no longer recommended for new designs.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a single-channel half-bridge configuration with 1A current capability is required. Ensure the system voltage remains within the 6V to 15V operating range. Consider the thermal performance of the HRP7 package under continuous load conditions. Verify that the logic interface levels are compatible with the controlling microcontroller or driver circuit.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the BD6221 series of motor drivers from ROHM. It is functionally similar to the BD6221F-E2 but utilizes the HRP7 surface-mount package instead of the SOP-8 form factor. The series is designed for low-power motor control applications requiring integrated protection features.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The BD6221F-E2 is a related variant offering identical electrical specifications but in an SOP-8 package. Direct pin-to-pin substitution requires verifying the mechanical footprint differences between the HRP7 and SOP-8 packages.
