BM6248FS-E2

Overview

The BM6248FS-E2 is a three-phase brushless DC motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 13.5 V to 16.5 V, with a maximum rating of 16.5 V. The device delivers an output current of 1.5 A and features four outputs. It functions at a working frequency between 18 kHz and 22 kHz. The component supports a load voltage of up to 600 V and maintains a low operating power current of 2 mA. It is housed in an SSOP-A54-36 package for surface mount installation and operates reliably across a temperature range from -40°C to +125°C.

Feature Summary

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

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-A54-36 package dimensions align with the PCB footprint. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent damage. Cross-reference the 1.5 A output current capability with the thermal management strategy for the target application environment.

Selection Notes

Select this component when designing systems requiring a dedicated driver for three-phase BLDC fans operating on low-voltage DC supplies around 15 V. The integrated nature simplifies design by combining logic and power stages. Consider the 600 V load voltage rating for robustness against back-EMF spikes. The wide operating temperature range suits various household appliance environments without requiring extensive external cooling solutions.

Part Context

This part belongs to ROHM's high-voltage three-phase brushless DC motor driver series. It shares architectural similarities with models like the BM6245FS-E2 and BM6242FS-E2 but differs in supply voltage specifications and package variants. The series targets home appliances, offering integrated solutions that reduce component count compared to discrete MOSFET implementations.
