FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTIONS
voltage with its analog-to-digital converter (ADC). This is
intended to provide the user with motor current feedback for
motor torque control. The resistance range for the linear
operation of the FB pin is 100 < R_FB < 200 Ω.
If PWM-ing is implemented using the disable pin inputs
(either D1 or D2), a small filter capacitor (1.0 µF or less) may
be required in parallel with the external resistor to ground for
fast spike suppression.
