BD6964FVM-TR

Overview

The BD6964FVM-TR is a single-phase brushless DC motor controller and driver manufactured by ROHM Semiconductor. It features a bridge-type output capable of delivering up to 800 mA of drive current. The device operates within a supply voltage range of 3.3 V to 14 V and supports PWM speed control via an external input signal. It functions at frequencies between 20 Hz and 50 kHz with a quiescent current of 5 mA. The component is housed in an 8-pin MSOP package, rated for power dissipation of 580 mW, and operates across a temperature range of -40°C to +105°C.

Feature Summary

• Supports PWM-based rotational speed control through external input signals
• Integrates bridge-type output drivers for single-phase BLDC applications
• Provides compact surface-mount packaging suitable for space-constrained designs

Applications

• Brushless DC motor speed regulation
• Small appliance motor control systems
• Automotive ignition or motion control circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration when sourcing. Confirm that the MSOP-8 pinout matches the target PCB footprint. Ensure the operating voltage requirements align with the 3.3 V to 14 V specification. Check for RoHS compliance documentation if required by project standards. Validate thermal management capabilities against the 580 mW power dissipation rating.

Selection Notes

Select this component for single-phase BLDC motor applications requiring integrated drive capability. Consider the 800 mA output limit for appropriate load sizing. Evaluate the MSOP-8 package for thermal performance in enclosed environments. Verify compatibility with PWM control signals within the specified frequency range. Assess the wide supply voltage range for flexibility in system design.
