TB6584AFNG

Overview

The TB6584AFNG is a three-phase brushless DC motor driver manufactured by Toshiba Semiconductor and Storage. It integrates control logic, gate drivers, and power output stages into a single SSOP-30 package. The device supports a maximum supply voltage of 16.5 V and delivers an output current of 1 A per phase. Operating at a typical supply current of 2 mA, it provides a compact solution for driving small brushless motors in applications requiring low power consumption and integrated protection features.

Feature Summary

• Integrates three-phase drive circuitry with built-in control logic
• Supports low standby current operation for energy efficiency
• Includes internal protection mechanisms against overcurrent and thermal issues

Applications

• Small cooling fans
• Hard disk drive spindle motors
• Office automation equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix codes match project requirements as they may indicate packaging variations. Check RoHS compliance status and ensure the part number corresponds to the exact revision needed for design compatibility.

Selection Notes

Select this component when designing systems requiring a dedicated three-phase BLDC driver with minimal external components. Ensure the load current does not exceed 1 A and the supply voltage remains within the 16.5 V limit. Consider thermal management solutions if operating near maximum ratings in enclosed environments.

Part Context

This part belongs to Toshiba's series of brushless motor controllers designed for consumer electronics and industrial peripherals. It replaces older discrete solutions by combining power MOSFETs and control ICs. The SSOP-30 package allows for space-constrained PCB layouts while maintaining reliable electrical performance for continuous motor operation.
