Motor drive output power supply and output current
detection
Connect a resistor (Rf) between this pin and VCC.
The output current will be limited to the value IOUT
= VRF/Rf.

Hall sensor inputs
"H" is the state where IN+ > IN-, and "L" is the
reverse state.
It is desirable that the Hall sensor signals have an
amplitude greater than 50 mVpp
If noise on the Hall sensor signals is a problem,
connect capacitors between the IN+ and IN- inputs.

HB
Hall sensor element bias current
This circuit is turned off in stop mode.

GND1
Control circuit block ground
12
PWM
Sets the PWM oscillator frequency.
Connect a capacitor between this pin and ground.
A 680pF capacitor sets the oscillator frequency to
be about 34kHz.
