BD6962FVM-TR

Overview

The BD6962FVM-TR is a single-phase full-wave motor driver designed for fan motors, manufactured by ROHM Semiconductor. It operates within an input voltage range of 3.3 V to 14 V and supports a maximum output current of 800 mA. The device features PWM speed control and a soft switching function to enhance performance. It is housed in an 8-pin MSOP package and supports surface mount installation. The component functions as a brushless DC motor controller with two outputs, operating at frequencies between 20 Hz and 50 kHz. Power dissipation is rated at 580 mW, with a quiescent current of 5 mA.

Feature Summary

• Integrates PWM speed control functionality for precise motor regulation
• Incorporates a soft switching function to reduce electrical noise and stress
• Supports single-phase full-wave drive topology for fan motor applications

Applications

• Brushless DC fan motor control systems
• Single-phase motor speed regulation circuits
• Electronic cooling devices requiring PWM control

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches exactly, as variations may exist without the trailing characters. Ensure the component meets RoHS compliance requirements for your project. Cross-reference the datasheet revision date to ensure compatibility with current design specifications. Validate the MSOP-8 package dimensions against your PCB footprint library before finalizing procurement.

Selection Notes

Select this component for applications requiring a dedicated single-phase driver with integrated PWM capabilities. It is suitable for low-voltage systems operating between 3.3 V and 14 V. Consider the 800 mA output limit when sizing for specific motor loads. The MSOP-8 package offers a compact solution for space-constrained designs. Evaluate the thermal performance given the 580 mW power dissipation rating under expected operating conditions.

Part Context

This part belongs to ROHM's line of motor drivers and controllers, specifically categorized under PMIC solutions. It serves as a specialized driver for single-phase brushless DC motors, distinct from general-purpose H-bridge drivers. The BD6962 series focuses on fan motor applications, offering integrated control features that simplify system architecture compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical parameter alignment if considering alternative manufacturers. Check for functional equivalence regarding PWM control and soft switching features. Ensure the replacement component supports the same 3.3 V to 14 V input range and 800 mA output capability.
