Product details
Overview
TB6586FG,C8,EL,HZ from Toshiba is a three-phase full-wave brushless DC motor controller IC designed for fan motor drive applications. It integrates Hall signal amplification, 120°/150° energization selection, lead angle correction (0–28°), built-in 5 V regulator (35 mA), and FG pulse output (1 pulse per 360° electrical angle). Operating from VCC = 6.5–16.5 V and VM = 4.5–16.5 V, it supports bootstrap gate driving and overcurrent protection via RS pin (0.5 V threshold).
For engineers reviewing the TB6586FG,C8,EL,HZ datasheet, TB6586FG,C8,EL,HZ pinout, TB6586FG,C8,EL,HZ application, or TB6586FG,C8,EL,HZ equivalent, key selection considerations include Hall-input hysteresis (±7.5 mV typ.), PWM carrier frequency tuning (via external R/C), VSP-based speed control (0–7 V analog input), and FG signal timing compatibility with 8-pole motor feedback (4 ppr).
Technical Context
The TB6586FG,C8,EL,HZ implements a sensor-based commutation architecture using differential Hall inputs (HUP/HUM, HVP/HVM, HWP/HWM) with 40 mVpp sensitivity and 1.5–3.5 V common-mode range. Its internal triangular-wave oscillator (2–8 MHz) feeds a PWM generator that drives six push-pull outputs (UH/UL, VH/VL, WH/WL) with ±3 mA drive capability and 95% max duty cycle.
Control logic includes dual energization modes (120° default at startup; 150° selectable via RESET pin), LA-pin analog lead angle setting (0–5 V → 0–28°), and system-level protections: VCC undervoltage lockout (6.0 V turn-on), RS-based overcurrent detection (0.5 V threshold with 0.5 μs analog filter), and position-error shutdown (all-Hall high/low/open).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 6.5–16.5 V: Powers internal logic and 5 V regulator; below 6.0 V disables outputs. |
| VM Range | 4.5–16.5 V: Supplies high-side driver power; must be ≥ VCC for bootstrap operation. |
| Vrefout | 5.0 V ±0.3 V @ 15 mA: Stable reference for Hall bias, LA, and CW/CCW inputs; not load-regulated beyond 35 mA. |
| FG Output | 1 pulse / 360° electrical angle: Digital push-pull signal (±2 mA) used for speed monitoring in 8-pole fans (4 ppr). |
| RS Threshold | 0.5 V (typ.): Triggers immediate gate-block protection on each PWM carrier cycle; immune to noise via 0.5 μs analog filter. |
| Oscillator Freq | 2–8 MHz: Set by external OSC/R (resistor) and OSC/C (capacitor); determines PWM carrier (fc = fosc/252). |
| Lead Angle Range | 0–28°: Linearly controlled by LA pin (0–5 V); enables torque optimization across speed/load conditions. |
Pinout & Package
Package: P-SSOP24-0613-1.00-001 (24-pin plastic shrink small outline package, 0.65 mm pitch, 7.8 × 4.4 × 1.0 mm, 0.36 g).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSP (1) | Speed command input | Analog voltage (0–7 V) controlling PWM duty; ≤1.0 V disables output; >2.1 V enables energization. |
| HUP/HUM (2/3), HVP/HVM (4/5), HWP/HWM (6/7) | Differential Hall sensor inputs | Accepts Hall element or IC outputs; 40 mVpp sensitivity, ±7.5 mV hysteresis, 1.5–3.5 V common-mode. |
| Vrefout (8) | Reference voltage output | 5.0 V supply for external Hall biasing and LA/CW/CCW interface; 35 mA max sink/source. |
| LA (9) | Lead angle control | 0–5 V analog input mapping linearly to 0–28° advance; enables efficiency tuning at varying loads. |
| GND (10) | Ground reference | Common return for logic, Hall, and regulator circuits; requires low-impedance PCB plane. |
| CW/CCW (11) | Direction control | Digital input: Low = forward (CW), High = reverse (CCW); ≥6.35 V triggers unstable system reset. |
| OSC/C & OSC/R (12/13) | Oscillator timing | External RC network sets 2–8 MHz clock; defines PWM carrier frequency (fc = fosc/252). |
| RS (14) | Overcurrent sense | Analog input monitoring shunt voltage; ≥0.5 V disables all high-side drivers per carrier cycle. |
| RESET (15) | Energization mode select | Low = 150° drive; High (≥6.35 V) = 120° drive; also forces output-off reset when pulled high. |
| VCC (16) | Logic supply | Powers internal circuitry and 5 V regulator; monitored for UVLO (6.0 V turn-on, 5.0 V turn-off). |
| VM (17) | Motor power rail | High-side driver supply; must exceed VCC to charge bootstrap capacitors for UH/VH/WH. |
| UL/VL/WL (18–20) | Low-side outputs | Push-pull drivers (±3 mA) for N-channel MOSFET gates; active during bootstrap charging phase. |
| UH/VH/WH (21–23) | High-side outputs | Bootstrap-driven push-pull outputs; require external high-side N-MOSFETs and floating supply. |
| FG (24) | Revolution pulse output | Digital tachometer signal: 1 pulse per 360° electrical angle (4 ppr for 8-pole motor). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Hall amplifier | Supports direct connection to Hall elements (not just Hall ICs); eliminates external op-amp stage and reduces BOM count. |
| Selectable commutation | Hardware-selectable 120° (default) or 150° energization via RESET pin; no firmware required for mode switching. |
| Bootstrap gate drive support | Built-in logic ensures reliable high-side N-MOSFET switching without external charge pumps or isolated supplies. |
| Lead angle correction | Analog LA input enables continuous 0–28° advance adjustment-critical for maintaining torque at low speeds and high loads. |
| Robust fault protection | Multi-layer safety: RS-based overcurrent, VCC UVLO, Hall-signal error detection, and output pulse-width limiting (<1 μs blocked). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC motor controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6584FG | No built-in 5 V regulator; requires external Vref; lacks LA pin for lead angle control. | Suitable only for fixed-advance designs; needs external Hall bias and reference supply. | Choose when cost reduction outweighs need for analog lead angle tuning and integrated regulation. |
| MP6532GQ-Z | Higher VM rating (28 V); integrated gate drivers with 1.2 A peak; no FG output or Hall amplifier. | Requires external Hall signal conditioning; targets higher-power fans (>30 W) with external MOSFETs. | Prefer when driving larger motors or needing higher VM headroom; not drop-in due to missing Hall amp and FG. |
Compared with TB6584FG, the TB6586FG,C8,EL,HZ adds integrated regulation and lead angle control-reducing external components and enabling dynamic efficiency tuning. Against MP6532GQ-Z, it trades higher VM tolerance for Hall-integration and tach output, making it optimal for compact, sensor-fed fan modules.

FAQ
What is the function of the FG pin on the TB6586FG,C8,EL,HZ?
The FG pin on the TB6586FG,C8,EL,HZ outputs a digital tachometer signal: one pulse per 360° electrical angle. For an 8-pole motor, this yields 4 pulses per mechanical revolution (4 ppr). The signal is push-pull (±2 mA), compatible with standard microcontroller counters, and remains active during RESET-induced output-off states-enabling continuous speed monitoring even during fault recovery.
How does the TB6586FG,C8,EL,HZ handle overcurrent protection?
The TB6586FG,C8,EL,HZ uses the RS pin for overcurrent detection: when the voltage at RS reaches 0.5 V (typ.), all high-side outputs (UH/VH/WH) are immediately disabled for that PWM carrier cycle. This analog threshold is filtered with a 0.5 μs time constant to reject noise. Protection resets automatically each cycle-allowing transient current spikes while blocking sustained overloads-and requires no external latch or MCU intervention.
Can the TB6586FG,C8,EL,HZ drive high-side P-channel MOSFETs?
No, the TB6586FG,C8,EL,HZ is designed exclusively for high-side N-channel MOSFETs using bootstrap gate driving. Its UH/VH/WH outputs are configured as floating-source drivers requiring external bootstrap capacitors and diodes. Driving P-channel devices would violate the IC's output architecture and disable critical features like automatic bootstrap charging during refresh operation (VSP = 1.0–2.1 V).
What is the minimum Hall signal frequency required for lead angle correction on the TB6586FG,C8,EL,HZ?
The TB6586FG,C8,EL,HZ activates lead angle correction only when the Hall signal frequency exceeds 5 Hz. Below this threshold-such as during startup or stall-the controller defaults to fixed 120° energization and ignores the LA pin input. This ensures stable initial rotation before transitioning to optimized commutation, and prevents erratic behavior during low-speed or reversing conditions.
How is the PWM carrier frequency set on the TB6586FG,C8,EL,HZ?
The PWM carrier frequency on the TB6586FG,C8,EL,HZ is derived from an external RC oscillator: fc = fosc / 252, where fosc is set by connecting a capacitor to OSC/C (pin 12) and a resistor to OSC/R (pin 13). With typical values (560 pF, 6.2 kΩ), fosc ≈ 5 MHz → fc ≈ 19.8 kHz. This allows precise EMI control and audible-noise suppression without requiring crystal or PLL circuitry.
