BA6254FS-E2

Overview

The BA6254FS-E2 is a brushless DC motor controller manufactured by ROHM Semiconductor. It operates with a supply voltage up to 310 V and delivers an output current of 1.5 A. The device features four outputs and functions at a working frequency of 20 kHz. It supports load voltages up to 600 V and has a maximum power supply rating of 400 V. The component operates within a temperature range of -40°C to +125°C and is housed in an SSOP-54 package.

Feature Summary

• Integrated control for three-phase brushless DC motors
• High voltage tolerance for industrial applications
• Surface mount packaging for automated assembly

Applications

• Industrial automation motor drives
• HVAC system fan control
• Appliance motor management

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SSOP-54 footprint matches your PCB design. Check humidity sensitivity levels if storage conditions exceed specified limits before reflow soldering.

Selection Notes

Select this component when a dedicated three-phase BLDC driver is required with high voltage capability. The integrated controller reduces external component count compared to discrete solutions. Verify that the 1.5 A output current meets the motor requirements under expected thermal conditions.

Part Context

This part belongs to ROHM's line of motor and motion controllers. It is designed for efficient drive of brushless DC motors in environments requiring robust voltage handling. The series typically integrates gate drivers and control logic to simplify system design.

Replacement Considerations

Cross-reference with BA6254FS for non-E2 variants. Verify functional equivalence with other ROHM BLDC controllers like BM6245FS-E2, ensuring package and electrical specifications align.
