Depletion-mode HEMT
Normally-on
– Essentially a resistor that can be turned-off with -gate bias
– Potential issues with power-up and power-down
– Requires additional master enable switch
– Requires negative gate drive
Low area specific on-resistance
Bi-directional conduction
– No intrinsic body diode
Can be made bi-directional blocking
Lateral device – monolithic integration possibilities
