High cost, EMI issue ADuM110+, ADuM5020 To take full advantage of a GaN transistor, the preferred requirements for isolated gate drivers are: Maximum allowable gate voltage 7 V 100 kV/ms dv/dt at switching node, 100 kV/µs to 200 kV/µs CMTI High-low switch delay match ≤50 ns for 650 V application Negative voltage clamp (–3 V) for turning offThere are several solutions to drive both the high-side and low-side of the half-bridge transistor. One myth about the traditional, level-shifted, high voltage driver is that the simplest single-chip implementation is widely used only for silicon-ba...
