The MAX5079 controllers on the EV kit monitor the respective input voltages at VIN1 and VIN2 with respect to the power bus voltage VBUS. When the VIN_ voltage rises above the VBUS voltage, the MOSFET is quickly turned on. If either VIN_ power-supply voltage falls below VBUS, the MAX5079 discharges the MOSFET gate with 2A (typ) sink current and turns off the MOSFET within 200ns (typ), effectively isolating the bus.
