BA6222

Overview

The BA6222 is a full-bridge motor driver IC designed for brushed DC motor applications, supporting output currents up to 2.2A. It features four operational modes: normal, reverse, stop, and braking, controlled by two input logic signals. The device includes a built-in thermal shutdown circuit for protection. A reference voltage setting pin allows optional output voltage configuration. High gain of 11.4dB enables high output voltage from low voltage inputs.

Feature Summary

• Full-bridge driver architecture for brushed motors with four distinct output modes
• Built-in thermal shutdown circuit for overtemperature protection
• Configurable output voltage via external reference voltage setting pin
• High gain amplification allowing high output voltage from low voltage control inputs

Applications

• Audio-visual equipment
• PC peripherals
• Car audio systems
• Car navigation systems
• Office automation equipment

Procurement Notes

Verify the specific datasheet version and package type before procurement, as Rohm may offer variations or updated revisions of the BA6222 series. Confirm that the intended application current does not exceed the 2.2A limit without adequate thermal management. Ensure compatibility with the required input logic levels and reference voltage settings for the specific design implementation.

Selection Notes

Select the BA6222 when a single-chip solution for reversible brushed DC motor control is required. It is suitable for applications needing simple two-input logic control for direction and speed (via PWM if supported by external circuitry) along with braking capabilities. Consider its thermal performance and the need for an external reference voltage if precise output voltage regulation is necessary for the load.

Part Context

The BA6222 belongs to ROHM's series of reversible motor drivers capable of handling currents of 2.0A or more. It is part of their portfolio aimed at simplifying motor control in consumer electronics and automotive accessories. Similar parts in the family include the BA6285FS and BA6951FS, which may offer different packaging or slight parameter variations while maintaining similar full-bridge functionality.

Replacement Considerations

Direct substitutes include other ROHM full-bridge drivers like the BA6285FS or BA6951FS. Cross-manufacturer replacements should be verified for pin compatibility, current rating, and thermal characteristics. Ensure any replacement supports the same four-mode operation and input logic requirements.
