BH6789FVM-GTR

Overview

The BH6789FVM-GTR is a single-phase brushless DC motor controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2 V to 6 V and draws a typical operating current of 5 mA. The device features two outputs with a maximum output current of 1 A per channel. It is housed in an 8-lead MSOP package and supports surface mount installation. The component functions reliably across an extended temperature range from -40°C to +105°C, with a power dissipation rating of 585 mW.

Feature Summary

• Integrated control and driver circuitry for single-phase BLDC motors
• Low power consumption suitable for battery-operated applications
• Compact surface-mount packaging for space-constrained designs

Applications

• Fan motor drivers
• Small appliance motor control
• Battery-powered equipment

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating any new product development projects. Confirm that the MSOP-8 package dimensions align with existing PCB footprints. Ensure thermal management strategies account for the specified power dissipation limits under maximum load conditions.

Selection Notes

Select this component for applications requiring low-voltage operation and minimal quiescent current. The single-phase architecture suits specific motor types where three-phase solutions are unnecessary. Evaluate the 1 A output capability against peak motor startup currents to ensure adequate headroom without exceeding thermal constraints.

Part Context

This part belongs to ROHM's line of motor motion controllers and drivers. It integrates gate drive and control logic into a compact form factor. The MSOP-8 package provides a balance between thermal performance and board space efficiency for consumer electronics.

Replacement Considerations

Check for updated ROHM components with active lifecycle status if long-term availability is required. Verify pin compatibility and electrical specifications when considering cross-brand alternatives.
