BM6242FS-E2

Overview

The BM6242FS-E2 is a three-phase brushless DC motor driver manufactured by ROHM Semiconductor. It integrates half-bridge outputs and PWM interface control within an SSOP-23 package. The device supports a supply voltage range of 13.5 V to 16.5 V, delivering an output current of 1.5 A. It operates reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates three-phase half-bridge power stages with PWM control logic for brushless DC motors
• Supports commutation and direction management functions
• Utilizes power MOSFET technology for efficient switching

Applications

• Fan motor drivers
• Air conditioner fan systems
• Purifier fan systems

Procurement Notes

Verify the specific suffix E2 against the manufacturer datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SSOP-23 package dimensions align with the PCB footprint. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing high-voltage BLDC applications requiring integrated commutation. The 1.5 A output current rating suits moderate load fan applications. Verify that the 13.5 V to 16.5 V supply range matches the system power architecture. Consider thermal dissipation capabilities within the SSOP-23 package for the target operating environment.

Part Context

This part belongs to the BM6242 series of high-voltage three-phase BLDC motor drivers from ROHM. These devices are designed for household appliances like air conditioners and purifiers. The series typically offers options for different current ratings and packages, with the BM6242FS-E2 providing a compact surface-mount solution.

Replacement Considerations

Check the BM6242FS (without E2) for legacy compatibility if the E2 suffix denotes a specific revision or packaging change. Consult the manufacturer's replacement guide for cross-references within the BM624x family.
