Abstract
An IC includes power and reference nodes, a protection circuit, and a gate driver. The protection circuit includes a series of diode-configured enhancement-mode n-type HEMTs coupled between the power and reference nodes and including a voltage tap, a first enhancement-mode n-type HEMT including a gate coupled to the voltage tap and a source terminal coupled to the reference node, and a second enhancement-mode n-type HEMT including a gate coupled to a drain terminal of the first n-type HEMT and a source terminal coupled to the reference node. The gate driver includes a third enhancement-mode n-type HEMT including a gate coupled to a drain terminal of the second n-type HEMT, a fourth enhancement-mode n-type HEMT including a gate coupled to a source terminal of the third n-type HEMT and a source terminal coupled to the reference node, and an output terminal coupled to a drain terminal of the fourth n-type HEMT.
