BA6849FS-E2

Overview

The BA6849FS-E2 is a three-phase brushless DC motor controller and driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 4.25 V to 5.5 V and features a pseudo-linear drive system. The device integrates power save, thermal shutdown, current limiter, and Hall sensor input functions. It is housed in a 24-pin SSOP package and supports surface mount installation.

Feature Summary

• Three-phase full-wave pseudo-linear drive system
• Integrated power save mode for efficiency
• Built-in thermal shutdown protection
• Current limiter and Hall sensor inputs

Applications

• Brushless DC motor control in home appliances
• Fan speed regulation systems
• Industrial automation motor drivers

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure compatibility with your microcontroller's logic levels and check for any recent lifecycle status changes such as NRND or obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a low-voltage (5V) three-phase BLDC driver is required. It is suitable for applications needing integrated protection features like thermal shutdown and current limiting without external discrete components. Consider the SSOP-24 package size constraints during PCB layout planning.

Part Context

This part belongs to ROHM's BA series of motor drivers, specifically designed for three-phase brushless DC motors. It simplifies motor control designs by integrating gate driving and protection circuits into a single IC, reducing board space and component count compared to discrete solutions.

Replacement Considerations

Check for direct substitutes within the BA68xx series from ROHM. Verify pin-to-pin compatibility and electrical ratings if considering alternative manufacturers. No specific cross-references are confirmed in public documentation.
