(a) DC excitation time
Duty cycle is determined by the gradient of SC terminal voltage, which depends on the charging of a
capacitor.
This voltage is clamped when the output duty cycle reaches about 35% for the de-excitation and
over-current protection.
When CW = U-phase → V-phase
When CCW = U-phase → W-phase
Preliminary
Ta (typ.) = 2.3 × CIP × RST (s)
(b) Forced commutation time
The forced commutation is started when the IP pin voltage falls below to 0.5 V or lower.
The output duty cycle of forced commutation is determined by VSP input voltage.
FST = High
: Forced commutation frequency fST = fosc/(6 × 217)
FST = Middle : Forced commutation frequency fST = fosc/(6 × 218)
FST = Low
: Forced commutation frequency fST = fosc/(6 × 219)
Example)
When fOSC = 5 MHz,
FST = High : fST ∼− 6.4 (Hz)
FST = Middle : fST ∼− 3.2 (Hz)
FST = Low or Open : fST ∼− 1.6 (Hz)
The rotor is aligned to a certain position specified in DC excitation mode for the period of (a), during which
the IP pin voltage decreases from Vrefout to 0.5 V. The time constant for the period is determined by CIP
and RST. After that, operation mode is switched to forced commutation mode (b) as shown above. The duty
cycle for DC excitation mode is determined according to the SC pin voltage. And after the IP pin voltage
falls to 0.5 V or lower, the duty cycle is determined according to the VSP pin voltage. When the rotational
frequency exceeds the forced commutation frequency specified with the status of the FST pin, the operation
mode is switched to the sensorless square-wave mode.
