TB6584AFNG
Functional Description
1. Basic Operation
During startup, the motor is driven by square-wave commutation signals that are generated according to
the position signals. When the position signals indicate a rotational speed (f) of 5 Hz, the TB6584AFNG
estimates the rotor positions from the position signals and modulate them. The TB6584AFNG then
generates sine-wave by comparing the modulated signals against a triangular waveform.
12
From startup to 5 Hz: square-wave drive (120° commutation); f = f / (2 × 32 × 6)
osc
5 Hz to: Sine-wave PWM drive (180° commutation); f will be approximately 5.7 Hz when f
= 4.5 MHz
osc
2. Voltage Command (VSP) Signal and Bootstrap Voltage Regulation
(1) When Vsp ≤ 1.0 V:
The commutation signal outputs are disabled (i.e., gate protection is activated).
(2) When 1.0 V < Vsp ≤ 2.1 V:
The low-side commutation signal outputs are turned on at a regular (PWM carrier) frequency. (The
conduction duty cycle is approx. 8%.)
(3) When 2.1 V < Vsp ≤ 7.3 V:
During sine-wave PWM drive, the commutation signals directly appear externally. During
square-wave drive, the low-side commutation signal outputs are forced on at a regular (PWM carrier)
frequency. (The conduction duty is approx. 8%.)
(4) When 8.2 V ≤ Vsp ≤ 10 V (test mode):
The TB6584AFNG drives in sine-wave drive mode with lead angle of zero. However, it drives in
square-wave mode in detecting reverse rotation.
When Vsp reaches 7.9 V (typ.), lead angle switches to zero.
The PWM duty is calculated as PWM_carrier_frequency × 92% (typ.) and kept the constant value (5.4
V≤ Vsp (typ.)).

3. Dead Time Insertion (cross conduction protection)
To prevent a short-circuit between external low-side and high-side power elements during sine-wave PWM
drive, a dead time is digitally inserted between the turn-on of one side and the turn-off of the other side.
(The dead time is also implemented at the full duty cycle during square-wave drive.)

level on the LA input, which works with 0 to 5 V.

7. Rotating Pulse Output
The TB6584AFNG outputs rotating pulse based on hall signal. FGC terminal can switch one pulse per
electrical angle or 3 pulses per electrical angle. One pulse per electrical angle is generated from hall signal
of U phase. 3 pulses per electrical angle are generated by combining each rising and falling edge of U, V, and
W phases.

8. Protection-Related Input Pins
(1) Overcurrent protection (Idc pin)
If the voltage of the DC-link current exceeds the internal reference voltage, the commutation signals
are forced Low. Overcurrent protection is disabled after every carrier period.
Reference voltage = 0.5 V (typ.)
(2) Gate block protection (RES pin)
When the RES input is High, the commutation outputs are disabled. When the RES input is then set
Low or OPEN, the commutation outputs are re-enabled.
Any irregular conditions of the motor should be detected by external hardware; such indications
should be presented to the RES input.

Abnormal position signal protection
When the position signal inputs (UVW) are all Highs or all Lows, the commutation outputs are
forced off (i.e., set Low). When these inputs are then set to any other combination, the commutation
outputs are re-enabled. (The all-High and all-Low conditions are internal hall amplifier outputs.)

The position signals from Hall sensors are modulated, and the modulated signals are then compared against a
triangular waveform to generate a sinusoidal PWM waveform.
The counter measures the period from a given rising (falling) edge of three hall signals to its next falling (rising)
edge (60 electrical degrees). This period is then used as 60° phase data for the next modulation.
A total of 32 ticks comprise 60 electrical degrees; the length of a tick equals 1/32nds the time period of the
immediately preceding 60° phase.

Phase of data and modulated waveform is adjusted for every zero cross of position detecting signal.
Modulation is reset on each rising and falling edge of position detecting signal, which occurs every 60 electrical
degrees. While the hall signal is out of its position and the motor is accelerating or decelerating, the modulated
waveform becomes discontinuous upon each reset.
Note: In the above diagram, hall signals are shown as square waveforms for the sake of simplicity.

IC Usage Considerations
Notes on handling of ICs
(1) The absolute maximum ratings of a semiconductor device are a set of ratings that must not be
exceeded, even for a moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
(2) Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case
of over current and/or IC failure. The IC will fully break down when used under conditions that exceed
its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise
occurs from the wiring or load, causing a large current to continuously flow and the breakdown can
lead smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown,
appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required.
(3) If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the
design to prevent device malfunction or breakdown caused by the current resulting from the inrush
current at power ON or the negative current resulting from the back electromotive force at power OFF.
IC breakdown may cause injury, smoke or ignition.
Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable,
the protection function may not operate, causing IC breakdown. IC breakdown may cause injury,
smoke or ignition.
(4) Do not insert devices in the wrong orientation or incorrectly.
Make sure that the positive and negative terminals of power supplies are connected properly.
Otherwise, the current or power consumption may exceed the absolute maximum rating, and
exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation or
incorrectly even just one time.
Points to Remember on Handling of ICs
(1) Over current protection circuit
Over current protection circuits (referred to as current limiter circuits) do not necessarily protect ICs
under all circumstances. If the Over current protection circuits operate against the over current, clear
the over current status immediately.
Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings
can cause the over current protection circuit to not operate properly or IC breakdown before operation.
In addition, depending on the method of use and usage conditions, if over current continues to flow for
a long time after operation, the IC may generate heat resulting in breakdown.
(2) Heat radiation design
In using an IC with large current flow such as power amp, regulator or driver, please design the device
so that heat is appropriately radiated, not to exceed the specified junction temperature (TJ) at any
time and condition. These ICs generate heat even during normal use. An inadequate IC heat radiation
design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown. In addition,
please design the device taking into considerate the effect of IC heat radiation with peripheral
components.
(3) Back-EMF
When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the
motor’s power supply due to the effect of back-EMF. If the current sink capability of the power supply
is small, the device’s motor power supply and output pins might be exposed to conditions beyond
absolute maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in
system design.
