BA6247

Overview

The BA6247 is a brushless DC motor controller manufactured by ROHM Semiconductor. It is designed for three-phase brushless fan motor drivers, supporting operation with Hall sensors. The device accommodates voltage ranges of 250 V or 600 V breakdown and provides output currents between 1.5 A and 2.5 A. It supports commutation angles of 120°, 150°, and 180° (sine wave drive). The component operates within a temperature range of -40°C to +125°C and is housed in an SSOP-A54 package.

Feature Summary

Compatible with motors equipped with Hall sensors
Supports multiple commutation angles including 120°, 150°, and 180° sine wave drive
Integrated surge absorption diodes
Built-in power save circuit to suppress current consumption during motor idle

Applications

Fan motors for air conditioners
Fan motors for air purifiers
Residential equipment fan motors

Procurement Notes

Verify the specific suffix and voltage rating (250V vs 600V) against the official datasheet before procurement, as variants exist within the family. Confirm the package type matches the design requirements. Check for end-of-life status or alternative recommendations from the manufacturer if the part is discontinued. Ensure compatibility with the target motor's Hall sensor configuration.

Selection Notes

Select this component for applications requiring high-voltage brushless DC motor control with integrated Hall sensor support. Consider the available commutation modes (120°, 150°, 180°) based on the desired noise and torque characteristics. Verify that the required output current falls within the 1.5 A to 2.5 A range. Ensure the operating environment temperature is within the specified -40°C to +125°C limits.

Part Context

The BA6247 belongs to ROHM's series of high-voltage three-phase DC brushless motor drivers. This family includes variants like BM6247FS and BA6243FS, differentiated by voltage ratings and output capabilities. These components are specifically engineered for residential appliances, focusing on efficiency and reliability in fan motor applications. The series emphasizes ease of use with built-in protection features and flexible commutation options.
