3-phase motor driver output
Minimum potential of 3-phase motor driver
output transistor.
Constant current control is made through
detection of this voltage. The current limiter
also functions by detecting this potential.
Power supply
Motor coil neutral point input pin.
The coil voltage waveform is detected with
reference to this voltage.
Coil waveform detection comparator input pin.
This pin is connected to each phase output
through the internal 10kΩ resistor.
Triangular wave generating capacitor
connection pin.
This triangular wave performs soft-switching of
the coil output waveforms.
In the VCO circuit, the operation frequency
range and minimum operation frequency are
determined by means of the capacitor value
connected this pin and ground.
VCO circuit voltage input pin.
The PCOUT pin voltage is input via CR filter.
