HA13563/V

KT : Torque constant (N•m/A)

TL : Rated load torque (N•m)

VOSC : PWM carrier oscillator amplitude (VPP, See the Electrical Charasteristics)

VE : Motor back EMF (VPP/T–T)

RNF : Current detection resistor (Ω)

Vref1 : Current limiter reference voltage (See the Electrical Charasteristics)

Vsat : Saturation voltage (See the Electrical Charasteristics)

Set C2 and derive the integration constants from the following formulas.

R4 = 1

ωP ⋅ C2

R2 = R4

C1 =

2 ⋅ R2 ⋅ ωO

(7)

R3 = R2

Next, determine R1 to match the phase of PLL output.

R1 =

1.89 ⋅ R4

1.6 − 0.33 ⋅ R4 / R2

(9)

When log ωP/ωM is greater than 2, a phase advance to compensate for this phenomenon is

required. Use the following formula to set the phase advance:

2. The Hall output bias voltage is determined by R101 and R102.

3. The output current is controlled according to the following formula:

Iomax = Vref1

RNF

Where, Vref1 is the current limiter reference voltage. (See the Electrical Charasteristics)

Mount this resistor as close as possible to the IC and use a resistor with a small inductance

component.

4. Connect these components as close to the IC as possible.
