R4 = ω P C2 (5) R2 = R4 G (E) C = 2 R2 ω O (6) (7) R3 = R2 (8) Next, determine R to match the phase of PLL output. R =.89 R R4 / R2 (9) When log ω P /ω M is greater than 2, a phase advance to compensate for this phenomenon is required.

The Hall output bias voltage is determined by R and R2. 3. The output current is controlled according to the following formula: Iomax = Vref R NF Where, Vref 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. 7

T MASK (sec) = 2 CLK D2 CLK D2 where, CLK : The reference frequency. D2 : CLK frequency dividing ratio. FG signal wave shaping output T MASK T MASK After digital filter 6. The PWM carrier frequency is determined roughly by the following formula: f PWM = 8 Rt (kω) Ct (pf) 3 7. The formula shown below roughly determines the time, Tprot (s), until the stuck rotor protection circuit operates. Figure 2 shows the operating waveforms. The latched state can be cleared by either CE or V CC. Note that a capacitor with a leakage current sufficiently smaller than the charging current Ict+ must be used.

V IL ).5 (kω) where, V IH : The clock driver high-level voltage. V IL : The clock driver low-level voltage. If an external clock signal is input to pin 6 through a capacitor (Cosc), we recommend using a pf capacitor for Cosc. 9. The relationship with CLK crystal oscillator frequency refer to the following.
