... Gate Drive The ISL6401 is capable of sourcing 1A of peak-drive current. Separate collector supply (PV pins help isolate the IC’s analog circuitry from the high power gate drive noise. To limit the peak current through the IC, an external resistor is placed between the totem-pole output of the IC and the gate of the MOSFET ...
