Motor drive output
Motor drive output system ground
Low side output transistor drive current supply
Motor drive output power supply and output current
detection.
Connect a resistor (Rf) between this pin and V CC .
The output current is limited to a value determined
by the equation I OUT = VRF/Rf.
Power supply
(Systems other than the motor drive output)
5V regulator output
Connect a capacitor (about 0.1µF) between this pin and
ground for stabilization.
