Application Information
1. Current Drive Output Current Setting
Motor current is determined by ISH/IAE voltage and Rs sensing resistance and calculated by the formula below considering
Rw. Generally internal bonding and metal resistance Rw is around 0.05
.
2. Current Drive Block1(CH5)
If there is no capacitor on the exterior of the FC terminal or low capacitance is used, it may cause oscillation or overshoot at
output terminal. The output stage will not be operating until FC1 terminal voltage reaches around 0.7V (Typical)
The output response time depends on the FC1 capacitance and interval of Input signal. Generally, the quick charging time is
10us~20us. To minimize the delay time difference in the output response between high-speed shutter and bulb shutter a quick
charging circuit is built in.
