Product details

Overview

TB67B054FTG from Toshiba Electronic Devices & Storage Corporation is a three-phase full-wave brushless DC motor controller IC designed for sine-wave PWM drive of motor fans. It features 6–16.5 V operating supply, 0°–58° programmable lead angle control in 32 steps, internal 5 V reference regulator (30 mA), and Hall-input-based position estimation for 120°/180° commutation switching at ≥5.7 Hz.

For engineers reviewing the TB67B054FTG datasheet, TB67B054FTG pinout, TB67B054FTG application, or TB67B054FTG equivalent, key selection considerations include its integrated triangular-wave generator (f_osc/252), dead-time-controlled six-output gate driver architecture, auto/manual lead angle mode, current-limiting Idc input with 0.5 V threshold, and FG/REV diagnostic outputs for fan speed and reverse-rotation detection.

Technical Context

The TB67B054FTG implements sensor-based commutation using three Hall inputs (HUP/HVP/HWP) to estimate rotor position and switch between square-wave (120°) startup mode below 5.7 Hz and sine-wave PWM (180°) drive above that threshold. Its internal 5-bit ADC digitizes LA voltage for precise lead-angle setting, while the 6-bit triangular-wave generator provides carrier frequency f_osc/252 for modulation.

Dead time (≈2.0 μs at f_osc = 4.5 MHz) is digitally inserted between high-side and low-side output transitions to prevent shoot-through. The IC integrates protection logic including overcurrent detection on Idc, gate-block disable via RES, abnormal Hall pattern detection (all-H/all-L), and under-voltage lockout with 4.0–4.5 V hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	VCC = 6 V to 16.5 V - powers internal logic, regulators, and output drivers; supports common 12 V fan rails.
Reference Output	Vrefout = 5.0 V (±0.5 V), 30 mA max - supplies stable bias for external analog circuitry and internal comparators.
Lead Angle Range	0° to 58° in 32 steps - adjustable via LA pin (0–5 V); enables torque optimization across speed/load conditions.
Carrier Frequency	f_osc/252 Hz (e.g., 20 kHz at f_osc = 4.5 MHz) - sets PWM switching rate for sine-wave generation and low-side refresh timing.
Dead Time	1.7–2.3 μs - prevents cross-conduction in external half-bridge power stages during PWM transitions.
Current Limit Threshold	Idc = 0.5 V (typ.) - triggers commutation disable when DC-link current exceeds safe level; resets each carrier cycle.
FG Output	2 pulses per electrical revolution - provides direct RPM feedback for closed-loop speed control in fan applications.

Pinout & Package

P-VQFN32-0505-0.50-005: 5 mm × 5 mm, 0.5 mm pitch, 32-pin exposed-pad QFN package; thermal resistance R_th(j-a) = 29.9°C/W on 4-layer FR4 board.

Pin/Terminal	Circuit Role	Design Meaning
U, V, W	High-side commutation outputs	Push-pull, Vrefout-referenced; drive external high-side MOSFET gates in 3-phase bridge.
X, Y, Z	Low-side commutation outputs	Push-pull, Vrefout-referenced; provide 8% duty-cycle bootstrap refresh during square-wave mode.
HUP, HVP, HWP	Hall sensor inputs	Differential digital inputs with ±7.5 mV hysteresis; enable rotor position sensing and commutation timing.
LA, UL, ALA	Lead angle control interface	LA: 0–5 V sets angle; UL: clips max angle; ALA: selects 60° vs. 360° modulation period for auto-mode.
Idc	Current limit monitor input	Analog input with 1 μs RC + digital filtering; disables outputs if >0.5 V (i.e., overcurrent condition).
RES	Reset input	Active-high; forces all U/V/W/X/Y/Z outputs low and halts commutation until pulled low or open.
FG, REV	Diagnostic outputs	FG: 2-pulse/elec. rev for speed; REV: push-pull flag indicating reverse rotation detected.
Vrefout	Internal reference output	5 V regulated supply; powers external filters, comparators, and LA/UL/ALA circuits; requires local decoupling.

Key Features

Feature	Design Value
Sine-wave PWM drive	Generates smooth sinusoidal phase voltages above 5.7 Hz, reducing acoustic noise and torque ripple in fan motors.
Auto/manual lead angle control	Enables real-time optimization of back-EMF alignment-either externally via LA voltage or automatically via Idc/Vsp feedback.
Integrated triangular-wave generator	Provides precise carrier waveform (f_osc/252) for PWM modulation without external oscillator components.
Dual commutation modes	Seamlessly transitions from robust 120° square-wave startup to efficient 180° sine-wave operation as motor speed increases.
Comprehensive protection suite	Includes overcurrent (Idc), gate-block (RES), Hall fault (all-H/all-L), and UVLO-reducing need for external safety circuitry.

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
STSPIN32F0A	Integrated 32-bit ARM Cortex-M0 MCU + gate drivers; requires firmware development; no native Hall-based sine-wave modulator.	Best for designs needing field-oriented control (FOC), custom diagnostics, or multi-motor coordination.	Choose STSPIN32F0A when software-defined control and FOC implementation outweigh the benefit of TB67B054FTG's plug-and-play sine-wave generation.
MP6532	Three-phase gate driver only (no Hall interface, no sine-wave generator, no Vrefout); requires external MCU and current sense.	Suitable for cost-sensitive, MCU-based systems where all control logic resides externally.	Choose MP6532 when full control flexibility is required and external microcontroller resources are available for commutation and protection logic.

Compared with STSPIN32F0A and MP6532, the TB67B054FTG delivers turnkey Hall-sensor-driven sine-wave PWM with integrated regulation and diagnostics-eliminating MCU dependency and reducing layout complexity for fan-specific applications.

FAQ

What is the function of the ALA pin on the TB67B054FTG?

The ALA pin on the TB67B054FTG selects the modulation period for auto lead angle control: logic low (or open) configures 60°-based modulation using both Idc and Vsp feedback, while logic high configures 360°-based modulation using Idc only. This directly determines how frequently the TB67B054FTG updates its lead angle calculation during motor rotation, enabling optimized torque response across varying loads.

How does the TB67B054FTG handle motor startup and commutation mode switching?

The TB67B054FTG starts in 120° square-wave commutation mode when Hall input frequency is below 5.7 Hz, then automatically switches to 180° sine-wave PWM drive above that threshold. This transition is fully hardware-based and requires no external intervention-ensuring reliable startup and smooth acceleration in fan applications where the TB67B054FTG operates without firmware.

What protection features are integrated into the TB67B054FTG?

The TB67B054FTG integrates overcurrent protection (via Idc input), gate-block disable (via RES pin), abnormal Hall pattern detection (all-H or all-L inputs), and under-voltage lockout (VCC monitor with 4.0–4.5 V hysteresis). These functions act autonomously to force outputs low or high-impedance, preventing damage to external power devices and ensuring safe operation without external supervision circuitry.

Can the TB67B054FTG drive motors without an external microcontroller?

Yes-the TB67B054FTG is a standalone three-phase BLDC controller requiring only Hall sensors, power supply, and basic analog inputs (Vsp, LA, Idc). It performs position estimation, sine-wave modulation, dead-time insertion, and protection entirely in hardware. No external microcontroller is needed for basic operation, making it ideal for cost-sensitive, firmware-free fan control using the TB67B054FTG.

What is the purpose of the FG and REV pins on the TB67B054FTG?

The FG pin outputs two pulses per electrical revolution for accurate RPM measurement, while the REV pin asserts low when reverse rotation is detected-both are push-pull digital outputs referenced to Vrefout. These signals provide essential closed-loop feedback and safety monitoring in fan systems, allowing host controllers to verify direction and speed without additional sensors, directly leveraging the TB67B054FTG's internal Hall processing.
