An internal charge pump drives the gate of the power device, allowing a very low on-resistance DMOS power FET of just

The source is protected from the VCC input being too low or too high. Under Voltage Lockout UVLO assures that VCC is above the minimum operating threshold, before the power device is turned on. If VCC goes above the high output threshold, the source voltage will be limited.
