Ground
Connect the ground side of the external resistor Rf to this pin.
Output current detection
Connect the low-resistance resistor RF between this pin and
ground.
The maximum output current is determined by the equation
I
Outputs
(Low side n-channel power FET gate drive outputs)
The duty is controlled.
