Functional Description
1. Basic operation
At startup, the motor runs at 120° energization. When the position detection signal reaches a revolution
count of fs = 5 Hz or higher, the rotor position is extrapolated from the position detection signal and output
is activated using the lead angle based on the LA signal.
Startup - 5 Hz: 120° energization
fs = f
/ (120 × 25 × 28)
osc
5 Hz or higher: 120° energization or 150° energization *
Approximately 5 Hz if f
= 5 MHz.
osc
*: At 5 Hz or higher, operation is performed in accordance with commands from RESET and LA pins.
When the motor is running at 5 Hz or lower and in reverse (in accordance with the timing chart), it will
be driven at 120° energization for a lead angle of 0°.

bootstrap method.

*: The lead angle correction (LA pin) function does not operate when the Hall signal is 5 Hz or less. The
lead angle correction function also does not operate when in a reverse detection state.
4. Correcting the lead angle
The lead angle can be corrected in the turn-on signal range from 0 to 28° in relation to the induced voltage.

7. Revolution pulse output pin (the difference between TB6586FG and TB6586AFG)
This pin outputs the revolution pulses based on the Hall signal. The TB6586FG outputs one (1) pulse /
electrical angle and the TB6586AFG outputs three (3) pulses / electrical angle. In the case of the
TB6586FG, this pulse is generated via the U phase Hall signal. For a Hall element, the pulse is converted
to digital and then output. For a Hall IC, it is output in the equivalent waveform. In the case of the
TB6586AFG, the up-down edges of the U, V and W phase (respectively) are combined and then generated.
Example:
Number of FG pulses for an 8-pole motor:
• TB6586FG: 4 pulses per revolution (4 ppr)
• TB6586AFG: 12 pulses per revolution (12 ppr)

8. Protecting input pin
(1) Overcurrent protection (Pin RS)
When the DC link current exceeds the internal reference voltage, this pin performs gate block
protection. Overcurrent protection is restored for each carrier frequency.
The pin is equipped with a filter (analog filter = 0.5 µs (typ.)) that prevents malfunctioning due to
external noise.
(2) Position detection signal error protection
When the position detection signals are either all High, Low or Open, all the output is turned OFF
(all phases Low). Anything else results in a restart.
(3) Low power voltage protection (V
power monitor)
CC
If the operation voltage range is exceeded when the power is being turned on or off, all the output is
turned Low to prevent short circuit damage to the power element. Also, if 2.1 V or higher is input via
the V pin, and if the motor is not rotating (Hall signal = 5 Hz or less), then normal drive is restored
SP
after a refresh operation (1.5 ms (typ.)) is performed. However, operations cannot be guaranteed
during a power restoration as the circuitry will be unstable when the power is turned on.

(4) Output pulse width restriction
To prevent damage to the output driver (externally attached), the drive output signals (UH, VH, WH,
UL, VL, WL) are restricted from being output at a pulse width of 1 µs or less.
(5) Reset circuit
When 1.7 V (typ.) or more is input to the RESET pin, a reset will be performed with all output phases
being turned off (i.e., all phases Low). Output is also turned off if 6.35 V (typ.) or more is supplied to
the CW/CCW pin. However, do not use this method as the restoration obtained from it is unstable.
•
•
RESET pin: Output off reset
All output phases are turned Low and the externally connected power element is stopped. When
1.7 V or less is input, the power is restored. During the restoration, if 2.1 V or more is not input to
the V pin, and if the motor is not rotating (Hall signal = 5 Hz or less), a refresh operation will be
SP
performed (1.5 ms (typ.)). Normal drive will then be restored.
During the reset, the internal counter continues to operate and the FG signal continues to be
output.
CW/CCW pin: System reset
All output phases are turned Low and the externally connected power element is stopped.
Restoration takes place at an input of 6.35 V (typ.). However, operation after this kind of system
reset is unstable.
TB6586FG: During a system reset, the FG signal is output in compliance with the U-phase Hall
signal.
TB6586AFG: The FG signal is not output during a system reset.

Note:
Utmost care is necessary in the design of the output, V , V , and GND lines since the IC may be destroyed by short-circuiting between outputs, air contamination faults,
CC M
or faults due to improper grounding, or by short-circuiting between contiguous pins.
Add overcurrent protection such as a fuse to make the device drive normally should a current exceeding the maximum rating flow in the IC for any reason.

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] 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
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.
