Description

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.
