Note 1: These values determine the internal IC reference clock. Recommended values are required to be used for
external capacitor and resister in setting the carrier frequency at 20 KHz.
Note 2: These are used to determine the DC excitation time and duty cycle at startup. Since those required time and
duty cycle vary depending on the motor type, appropiate values must be determined through experiments.
Since the motor is driven by a minimum current, these must be connected as close as possible to the IC
lead.
Note 3: These capacitors are used for power supply stabilization. Appropriate values must be determined depending
on usage environment. These capacitors must also be connected as close as possible to the IC lead to
enhance noise rejection.
Note 4: The voltage generated at the phase current detection resistor R1 must be below 0.5 V.
Note 5: R2 and R3 should be adjusted so that the voltages generated at those resistors become half the voltages
generated at the induced voltage detection resistors, R4 and R5, respectively. Since these voltages are also
used for VM-power supply monitoring, ensure that VCC does not exceed the operating power-supply voltage
range. For a detailed functional description, refer to the functional description in Section 16, VCC-Power
Supply Monitoring.
Note 6: These resistors are used for the induced voltage detection in square-wave mode. Also, these resistors are
used for the detection of the voltage applied to the motor in sine-wave mode. R4 and R5 should be adjusted
so that the voltage applied to the TB6582FG becomes 4.5 V or lower.
Note 7: The time constant varies depending on the inductance and resistance of each motor. Thus, attach the motor
to the TB6582 and adjust the time constant experimentally. For more details, refer to the functional
description in Section 7, Induced Voltage Detection.
Note 8: The PWM signals generated from the output pins must be low-pass filtered to obtain linear voltages.
Note 9: This capacitor is used to specify the lead angle in sine-wave mode. For the automatic lead-angle correction,
the appropriate CLA should be used so that the U-phase current is delayed by the amount of time obtained
based on the calculated induced voltage. For more details, refer to the functional description in Section 8,
Lead Angle Correction.
