BM6244FS-E2

Overview

The BM6244FS-E2 is a three-phase brushless fan motor driver manufactured by ROHM Semiconductor. It operates within a power supply voltage range of 13.5 V to 16.5 V, with a maximum rating of 200 V and a typical operating voltage of 140 V. The device delivers an output current of 2 A and supports load voltages up to 250 V. It functions at a working frequency of 20 kHz with a quiescent supply current of 1.7 mA. The component is housed in an SSOP-54 surface-mount package and is rated for operation between -40°C and +125°C.

Feature Summary

• Integrated control and power stage for three-phase brushless DC motors
• Supports multiple commutation angles including 120°, 150°, and 180° (sine wave drive)
• Compatible with motors equipped with Hall sensors

Applications

• Fan motor drivers for air conditioners
• Fan motor drivers for air purifiers
• Fan motor drivers for residential equipment

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SSOP-54 package dimensions are compatible with the PCB footprint. Confirm moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this component when a 2 A output current capability is required for three-phase BLDC applications. It is suitable for systems operating with a nominal 140 V supply. Consider the thermal performance within the specified -40°C to +125°C range and the SSOP-54 package constraints for heat dissipation.
