Hall sensor inputs
A high-level state is recognized when IN+ > IN–, and a
low-level state is recognized under the reverse condition.
If noise on the Hall sensor signals becomes a problem,
insert capacitors between the IN+ and IN– inputs.
Control amplifier inputs
The PWMIN pin must be held at the low level for control
using this pin to function.
Control amplifier output
When the TOC pin voltage rises, the IC changes the UH,
VH, and WH output signal PWM duty to increase the
torque output.
Shared function pin: PWM oscillator frequency setting and
initial reset pulse generation
Insert a capacitor between this pin and ground.
A capacitor of 2000 pF sets a frequency of about 22 kHz.
Motor constraint detection output
This pin output is on when the motor is turning and off
when the constraint protection circuit operates.
