Product details

Overview

TB6584AFNG from Toshiba Electronic Devices & Storage Corporation is a 3-phase full-wave sine-wave PWM brushless DC motor controller IC designed for motor fan applications. It delivers 180° commutation with programmable lead angle (0°–58° in 32 steps), operates from 6 V to 16.5 V supply, integrates a 5 V reference voltage regulator (30 mA max), and supports Hall-effect position sensing with digital filtering on all six HU–HWM inputs.

For engineers reviewing the TB6584AFNG datasheet, TB6584AFNG pinout, TB6584AFNG application, or TB6584AFNG equivalent, this page provides verified functional context, confirmed pin roles (e.g., LA for lead-angle control, Idc for current-limiting, FGC for FG pulse selection), real-world timing behavior (startup square-wave → transition to sine-wave at ≥5.7 Hz), and validated alternative options for BLDC fan control systems requiring stable commutation and reverse-rotation detection.

Technical Context

The TB6584AFNG implements sensor-based rotor position estimation using three Hall inputs (HU/HV/HW and their complements HUM/HVM/HWM), generating modulated sine-wave drive signals via comparison against an internal triangular carrier waveform (f_osc/252). It transitions automatically from 120° square-wave startup (≤5 Hz) to 180° sine-wave PWM drive (≥5.7 Hz) based on measured Hall frequency.

Dead time (≈2.0 μs at f_osc = 4.5 MHz) is digitally inserted between high-side and low-side outputs to prevent shoot-through. Lead angle is controlled either externally via LA pin (0–5 V linear mapping) or internally via peak-hold circuitry, with upper limit set by UL pin. Reverse rotation is detected via dedicated REV push-pull output synchronized to electrical angle.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	VCC = 6 V to 16.5 V - powers internal logic, gate drivers, and 5 V regulator; undervoltage lockout activates below 4.0 V.
Reference Output	Vrefout = 5.0 V (±0.5 V), 30 mA max - supplies bias for external circuits and internal analog blocks (LA, Idc, UL).
Lead Angle Range	0° to 58° in 32 discrete steps - adjustable via LA pin voltage (0 V = 0°, 5 V = 58°); enables torque optimization across speed/load.
PWM Carrier Frequency	f_osc/252 Hz - derived from CR oscillator (3–6 MHz); e.g., 4.5 MHz → 17.86 kHz - sets minimum switching resolution and audible noise floor.
FG Output Options	1 ppr or 3 ppr selectable via FGC pin - 1 ppr uses U-phase Hall edge only; 3 ppr combines rising/falling edges of all three phases for higher-resolution speed feedback.
Current Limit Threshold	Idc = 0.5 V (typ.) - triggers overcurrent protection by forcing all commutation outputs low; includes 1 μs RC + 1 μs digital filtering.
Operating Temperature	−30°C to +115°C - rated for enclosed fan environments; thermal derating begins above 25°C ambient per PD–T_a curve.

Pinout & Package

Package: HTSSOP-30 (Thermally Enhanced Thin Shrink Small Outline Package), 30-pin, 0.5 mm pitch, exposed thermal pad. Weight: 0.17 g (typ.).

Pin/Terminal	Circuit Role	Design Meaning
1, 2	OSC/C, OSC/R	CR oscillator network - sets system clock (3–6 MHz); determines carrier frequency (f_osc/252) and dead time (9/f_osc).
3–8	HUP, HUM, HVP, HVM, HWP, HWM	Hall position inputs - differential-sense U/V/W phase and complement; include internal digital filters (~500 ns) and ±7.5 mV hysteresis.
10	RES	Active-low reset - L enables motor operation; H forces all U/V/W/X/Y/Z outputs low and halts bootstrap charging.
11	CW/CCW	Rotation direction select - L = clockwise; H = counterclockwise; internal pull-up; used with REV to detect reverse rotation.
12	Vsp	Voltage command input - 0–10 V range controls speed/torque; 1.0–2.1 V enables refresh mode; 5.4 V sets 92% PWM duty; ≥8.2 V enters test mode.
13, 14	LA, UL	Lead angle control - LA (0–5 V) sets angle step; UL clips maximum angle (0–5 V); both referenced to Vrefout.
15	LPF	RC low-pass filter capacitor terminal - internal 100 kΩ resistor forms filter with external cap (e.g., 0.1 μF) for LA signal conditioning.
16	FGC	FG pulse count select - H/OPEN = 3 ppr; L = 1 ppr; internal pull-up; enables flexible tachometer resolution matching.
17–19	PH, Gin, Gout	Peak-hold amplifier - PH holds Idc-derived voltage; Gin/Gout configure gain (up to 25 dB) for optimal LA response under load variation.
20	Idc	Current limit sense input - 0.5 V threshold; internal RC + digital filtering rejects noise; open-circuit disables all outputs.
21	VCC	Main power supply - 6–16.5 V; powers logic, drivers, and internal regulator; monitored for UVLO (4.0–4.5 V thresholds).
22	Vrefout	5 V reference output - supplies external bias and internal analog circuits; requires local 0.1 μF decoupling to prevent oscillation.
23–28	U, V, W, X, Y, Z	Commutation outputs - U/V/W = high-side; X/Y/Z = low-side; push-pull, ±2 mA drive; logic-level compatible with external gate drivers.
29	FG	Rotational pulse output - 1 or 3 pulses per electrical angle; push-pull, ±1 mA; used for closed-loop speed control or RPM monitoring.
30	REV	Reverse rotation flag - push-pull output; Low = forward (CW/CCW matches rotation); High = reverse; updated every 360° electrical.

Key Features

Feature	Design Value
Sine-wave PWM commutation	Enables smooth, low-noise, low-vibration motor operation above 5.7 Hz; eliminates torque ripple inherent in square-wave drives.
Auto-startup sequence	Initiates with 120° square-wave drive ≤5 Hz, then seamlessly transitions to 180° sine-wave PWM - ensures reliable start under load without external sequencing logic.
Dual-mode FG output	Selectable 1 ppr or 3 ppr via FGC pin - allows precise speed measurement in low-RPM fans (1 ppr) or high-resolution control in variable-speed systems (3 ppr).
Integrated lead angle control	Adjustable 0°–58° in 32 steps via LA pin or auto-mode - compensates for back-EMF phase lag across speed range, maximizing efficiency and torque.
Comprehensive protection suite	Includes overcurrent (Idc), gate block (RES), abnormal Hall (UVW = 000/111), and UVLO - reduces need for external fault-handling circuitry in fan modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase BLDC motor controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0A	Integrated 32-bit ARM Cortex-M0 MCU + gate drivers; requires firmware development; no native Hall-based sine-wave generation - relies on external ADC and software-based FOC.	Better for custom motion profiles and field-oriented control; less suitable for drop-in fan replacement due to code dependency and lack of auto-startup sequence.	Choose STSPIN32F0A when system-level intelligence (e.g., communication, diagnostics) is required beyond basic commutation.
MP6532	Standalone Hall-sensored BLDC controller; fixed 0°–30° lead angle range (vs. TB6584AFNG's 0°–58°); no FGC-selectable FG output; lower VCC max (15 V vs. 16.5 V).	Valid for cost-sensitive, lower-power fans where 30° lead angle suffices and 1 ppr FG resolution is acceptable.	Choose MP6532 only if lead angle headroom and FG flexibility are not design requirements - verify Idc threshold (0.4 V) and thermal limits match your layout.

Compared with STSPIN32F0A and MP6532, the TB6584AFNG offers the widest lead angle range (0°–58°), hardware-selectable FG resolution (1/3 ppr), and fully autonomous startup-to-sine-wave transition - making it uniquely suited for high-reliability, low-noise fan applications without firmware overhead.

FAQ

What is the startup behavior of the TB6584AFNG?

The TB6584AFNG initiates motor operation using 120° square-wave commutation when Hall input frequency is ≤5 Hz. Once rotational speed reaches ≈5.7 Hz (at f_osc = 4.5 MHz), it automatically transitions to 180° sine-wave PWM drive. This dual-mode behavior ensures reliable startup under load without external sequencing logic - a key feature of the TB6584AFNG architecture.

How does the TB6584AFNG implement lead angle control?

The TB6584AFNG supports two lead angle modes: external (via LA pin voltage 0–5 V, mapped linearly to 0°–58° in 32 steps) and automatic (LA pin left open, using internal peak-hold circuitry). The UL pin sets an upper voltage limit to clamp maximum angle. Both methods directly adjust commutation timing to compensate for back-EMF phase lag - a core function of the TB6584AFNG in maintaining torque efficiency.

What protection features are built into the TB6584AFNG?

The TB6584AFNG integrates overcurrent protection (Idc pin, 0.5 V threshold), gate-block protection (RES pin, active-high disable), abnormal Hall input detection (UVW = 000 or 111), and undervoltage lockout (VCC monitor, 4.0–4.5 V thresholds). All protections trigger hardware-level responses within microseconds - no firmware intervention required. These safeguards define the TB6584AFNG's suitability for safety-critical fan applications.

Can the TB6584AFNG drive motors without external gate drivers?

No - the TB6584AFNG outputs (U/V/W/X/Y/Z) are logic-level push-pull signals (±2 mA, V_OH = Vrefout − 0.78 V, V_OL = 0.78 V) intended to drive external N-channel high-side and low-side gate drivers or discrete MOSFETs. It does not integrate power-stage drivers. This architecture allows scalable power handling and thermal separation - a deliberate design choice in the TB6584AFNG specification.

How is reverse rotation detected using the TB6584AFNG?

Reverse rotation is detected by comparing the CW/CCW pin state with actual motor direction inferred from Hall signal sequence. When mismatch occurs (e.g., CW/CCW = Low but rotation is CCW), the REV pin asserts High every 360° electrical. This hardware-level flag enables immediate system-level response - such as alarm triggering or speed reduction - without software polling. The REV output is a defining capability of the TB6584AFNG in safety-aware designs.
