where Vref1 is the current limiter reference voltage (see Electrical Characteristics)
3. The burst time t1 is defined as follows:

Rt1'
ln (1 Vth1 (L) / Vreg) (RPM select input low)
t1
Ct
Rt1'
ln (1 Vth1 (H) / Vreg) (RPM select input high)
where Rt1' is resistance value inter 3 to 4 pin.
4. Place as close to the IC as possible.

Rt2'
ln (Vth1 / Vth2)
where Vth2 is the threshold voltage (see Electrical Characteristics).
Rt2' : Rt1 (max) + Rt2
7. If the circuit is affected by noise, a large capacitance value should be set.
