Product details
Overview
TB6584AFNG from Toshiba is a 3-phase full-wave sine-wave PWM brushless DC motor controller IC designed for motor fan applications. It supports 120° square-wave startup and seamless transition to 180° sine-wave commutation at ≥5.7 Hz, features programmable lead angle control (0°–58° in 32 steps), internal 5 V reference regulator (30 mA), and operates from 6–16.5 V supply.
For engineers reviewing the TB6584AFNG datasheet, TB6584AFNG pinout, TB6584AFNG application, or TB6584AFNG equivalent, key selection criteria include Hall-based rotor position estimation, dead-time-controlled 6-output gate drive (U/V/W/X/Y/Z), FG pulse output configurability (1 or 3 ppr), and real-time current-limiting via Idc input with 0.5 V threshold.
Technical Context
The TB6584AFNG implements sensor-based sinusoidal commutation using Hall inputs (HUP/HVP/HWP) to estimate rotor position and generate modulated waveforms compared against an on-chip triangular carrier (fosc/252). It integrates a 5-bit ADC for LA voltage conversion, peak-hold circuitry for adaptive lead angle tuning, and digital dead-time insertion (TOFF ≈ 2.0 μs @ fosc = 4.5 MHz) to prevent shoot-through.
Startup begins in 120° square-wave mode below ~5.7 Hz; above that threshold, it switches to 180° sine-wave PWM with automatic phase alignment. Lead angle is set externally via LA pin (0–5 V → 0°–58°) or auto-controlled, while Vsp (0–10 V) governs speed, conduction duty (up to 92%), and test-mode entry (8.2–10 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | VCC = 6–16.5 V - powers internal logic, gate drivers, and 5 V regulator; absolute max 18 V. |
| Oscillation Frequency | fosc = 3–6 MHz - sets carrier frequency (fosc/252) and timing resolution for modulation and dead time. |
| Lead Angle Range | 0° to 58° in 32 steps - adjustable via LA pin voltage (0–5 V); enables torque optimization across speed/load. |
| Commutation Outputs | 6 push-pull outputs (U/V/W/X/Y/Z) - high-side (U/V/W) and low-side (X/Y/Z) with ±2 mA drive, Vrefout-referenced levels. |
| Current Limit Threshold | Idc = 0.5 V (typ.) - disables outputs when DC-link current exceeds threshold; digital + analog filtering (1 μs each). |
| FG Output Configurability | 1 or 3 pulses per electrical revolution - selected by FGC pin; supports precise speed feedback in fan control loops. |
| Reference Voltage | Vrefout = 5.0 V ±0.5 V (30 mA max) - powers external circuits and references analog inputs (LA, UL, Vsp, Idc). |
Pinout & Package
Package: HSOP-30 (Heat Sink Over-molded Plastic), 30-pin, surface-mount, 0.17 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OSC/C, OSC/R | CR oscillator network - sets fosc (3–6 MHz); determines carrier frequency, dead time, and modulation timing. |
| 3–8 | HUP, HUM, HVP, HVM, HWP, HWM | Hall position inputs - differential sensing with ±7.5 mV hysteresis; UVW=111/000 triggers gate block protection. |
| 10 | RES | Active-low reset - forces all commutation outputs Low; internal pull-down enables safe stop-on-fault. |
| 11 | CW/CCW | Rotation direction select - L = clockwise, H = counterclockwise; internal pull-up simplifies MCU interface. |
| 12 | Vsp | Voltage command input - 0–10 V range controls speed, duty cycle (up to 92%), and enters test mode at ≥8.2 V. |
| 13, 14 | LA, UL | Lead angle control - LA (0–5 V) sets angle; UL caps maximum angle; both use internal 5-bit ADC. |
| 23–28 | U, V, W, X, Y, Z | 6-channel gate drive outputs - U/V/W = high-side, X/Y/Z = low-side; push-pull, Vrefout-referenced, ±2 mA. |
| 29, 30 | FG, REV | FG = speed feedback (1 or 3 ppr); REV = reverse rotation detection - push-pull, ±1 mA, used for safety interlocks. |
Key Features
| Feature | Design Value |
|---|---|
| Sine-wave PWM commutation | Enables smooth, low-noise, low-vibration motor operation above 5.7 Hz; reduces acoustic noise vs. square-wave in fan applications. |
| Auto-switching between 120° and 180° modes | Eliminates need for external mode control logic; transitions seamlessly at Hall frequency threshold (~5.7 Hz @ fosc=4.5 MHz). |
| Digital dead-time insertion | TOFF ≈ 2.0 μs @ fosc = 4.5 MHz prevents shoot-through in external half-bridge power stages without external timing components. |
| Integrated 5 V regulator | Vrefout = 5.0 V ±0.5 V / 30 mA - powers external Hall sensors, RC filters, and reference circuits; eliminates need for external LDO. |
| Real-time current limiting | Idc pin monitors DC-link current with 0.5 V threshold, dual-stage (analog + digital) filtering, and automatic recovery per carrier cycle. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0A | Integrated 32-bit ARM Cortex-M0+ MCU + gate drivers; requires firmware development; no built-in Hall position estimator. | Best for designs needing field-oriented control (FOC), variable-speed profiles, or communication interfaces (UART/SPI). | Choose STSPIN32F0A when algorithmic flexibility outweighs time-to-market; TB6584AFNG offers plug-and-play Hall-based sine-wave control. |
| MP6532 | 6-channel gate driver only - no Hall interface, no position estimation, no PWM generator; requires external MCU and commutation logic. | Suitable for custom FOC or trapezoidal implementations where full control over timing and modulation is required. | Choose MP6532 when integrating into existing MCU-based motor control stacks; TB6584AFNG delivers complete Hall-sensor-based solution in one IC. |

FAQ
What is the minimum Hall input frequency required for TB6584AFNG to enter sine-wave PWM mode?
The TB6584AFNG automatically transitions from 120° square-wave startup to 180° sine-wave PWM commutation when the Hall input frequency reaches approximately 5.7 Hz, assuming fosc = 4.5 MHz. Below this threshold, it remains in square-wave mode for reliable low-speed startup. This transition is fully internal and requires no external intervention or configuration change in the TB6584AFNG.
How does the TB6584AFNG implement dead-time control between high-side and low-side outputs?
The TB6584AFNG digitally inserts dead time (TOFF ≈ 2.0 μs at fosc = 4.5 MHz) between complementary high-side (U/V/W) and low-side (X/Y/Z) outputs to prevent shoot-through. TOFF = 9/fosc, making it directly scalable with oscillator frequency. This fixed-ratio digital implementation ensures consistent cross-conduction protection without external RC networks or calibration in the TB6584AFNG design.
Can the TB6584AFNG operate without connecting the LA (lead angle) pin?
Yes - leaving the LA pin open configures the TB6584AFNG for automatic lead angle control, where the internal circuitry dynamically adjusts lead angle based on motor back-EMF and speed. In this mode, LA pin voltage reflects real-time lead angle value and can be monitored externally. The TB6584AFNG continues full operation with optimized torque and efficiency without manual LA voltage setting.
What protection functions are integrated into the TB6584AFNG?
The TB6584AFNG integrates overcurrent protection (via Idc pin, 0.5 V threshold), gate-block protection (via UVW=111/000 detection), undervoltage lockout (VCC monitor with 4.0–4.5 V hysteresis), and reverse-rotation detection (REV pin). All protections trigger immediate output disable with automatic recovery where applicable - no external components are needed to implement these safety functions in the TB6584AFNG system.
What is the purpose of the LPF pin on the TB6584AFNG?
LPF is the RC low-pass filter capacitor terminal for the lead angle control loop. An external capacitor (recommended 0.1 μF) connects here, working with the on-chip 100 kΩ resistor to form a filter that stabilizes LA adjustment against noise and transient spikes. This ensures smooth, jitter-free lead angle response during dynamic load changes in the TB6584AFNG motor control system.
