BD6212HFP-TR

Overview

The BD6212HFP-TR is a fully integrated H-bridge motor driver IC designed for brushed DC motors. It operates within a supply voltage range of 3V to 7V and supports a maximum output current of 2A. The device utilizes Power MOSFET technology and features an On/Off interface for control. It is housed in an HRP-7 package with seven terminals and includes built-in protection circuits against overcurrent, overvoltage, and overheating.

Feature Summary

• Integrates two half-bridge outputs for complete H-bridge motor control
• Incorporates comprehensive protection mechanisms including overcurrent, overvoltage, and thermal shutdown
• Supports PWM input signals up to 100 kHz for speed regulation
• Designed for low power consumption and high efficiency in compact applications

Applications

• AV equipment such as DC and DVD players
• Media player devices requiring brushless or brushed DC motor control
• Compact consumer electronics utilizing small DC motors

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm that the 7V maximum supply voltage aligns with the target circuit design. Ensure the HRP-7 package dimensions fit the PCB layout constraints. Check RoHS compliance status if required by regional regulations. Validate that the 2A current rating meets the motor load requirements without exceeding thermal limits.

Selection Notes

Select this component for low-voltage applications requiring up to 7V operation. Choose the BD6212HFP-TR over higher voltage variants like the BD62321 series when system power is limited to 5V or 7V. Consider the 2A current capacity for moderate load motors. Opt for this part when integrated protection features are necessary to simplify system design compared to discrete solutions.

Part Context

The BD6212HFP-TR belongs to the ROHM BD621 series of H-bridge drivers. This family offers various supply voltage options including 7V, 18V, and 36V models. The BD6212 variant specifically targets lower voltage systems with a 2A output capability. It shares functional similarities with other members of the BD621x series but differs in voltage and current specifications.

Replacement Considerations

The BD6211HFP-TR is a compatible alternative within the same series offering similar functionality with a 1A output current rating. Both parts share the HRP-7 package and basic control interfaces. Designers should verify current requirements before substituting, as the BD6211 cannot handle the 2A load supported by the BD6212.
