2. The retract current is determined as follows.
Vretpow – Vsatret
Iret =
R101 + R_L + R_S
(7)
where,
R_L = VCM coil Resistor.
Vsatret = Retout saturation voltage (See electrical characteristics)
3. The motor start up current I_O is determined as follows.
Vref1
I_O = _RNF
(A)
(8)
Where, Vref1 = Current limiter reference voltage
(See electrical characteristics)
4. The power on reset delay time is determined as follows.
t_POR = 10⁵•C₁₀₇ (See electrical characteristics) (9)
