The OUTx pins of the device are connected to the gates of the external MOSFET transistors. The OUTx pin driver
circuits charge and discharge the MOSFET gate capacitance with a constant current source and sink. The supply
for the current source is the V5D pin. Internal resistors to ground are included on the OUTx pins so that the external
MOSFET is held in the off state when power is not applied to the device.
An external resistor is typically placed between the OUTx pin and the gate of the external MOSFET in order to set
the MOSFET turn-on and turn-off times. The value of the resistor must be chosen such that the turn-on and turn-
off times of the MOSFET are no longer than 1/(Fpwm*32).
