FGIN-
FG amplifier input.
Also serves as the Hall FG/pattern FG
switching pin.
When in Fall FG mode, connect this pin to
the VREG pin.
14
FGOUT
FG amplifier output
15
N
min 0.0V
max VCC
Divisor switching.
Low: 0.0V to 1.0V.
Medium: 2.0V to 3.0V.
High: 4.0V to VCC.
"M" is selected when this pin is held open.
16
BC
Brake control. Connect a capacitor
between this pin and ground.
Stopping characteristics of a motor is
controlled by adjusting the capacitance.
