Claim 10:
11. The IC of claim 10, wherein
the protection circuit further comprises a voltage divider configured to generate a fourth voltage based on the power supply voltage,
the first series of n-type HEMTs comprises a first depletion-mode n-type HEMT coupled between the power supply node and the first node and a first enhancement-mode n-type HEMT coupled between the first node and the power supply reference node,
the second series of n-type HEMTs comprises a second depletion-mode n-type HEMT coupled between the power supply node and the first output terminal and a second enhancement-mode n-type HEMT coupled between the first output terminal and the power supply reference node,
each of the first and second depletion-mode n-type HEMTs is configured as a diode,
the first enhancement-mode n-type HEMT comprises a gate configured to receive the fourth voltage, and
the second enhancement-mode n-type HEMT comprises a gate coupled to the first node.
