Besides, due to low threshold voltage and extremely fast switching transients, a negativeof voltage level may be needed. The widely used RC-coupled gate driver fulfils these requirements, however it suffers from a duty-cycle dependence of switching dynamics and the lack of negative gate drive in specific situations. Infineon s GaN EiceDRIVER solves these issues with very low effort. The two output stages shown below enable a zero of level to eliminate any duty-cycle dependence. In addition, the differential topology is able to provide negative gate drive without the need for a negative supply voltage. However, it requires a floating supply voltage not compatible with bootstrapping.
