CoolGaN™ and similar GaN switches require a continuous gate current of a few mA in their on state. Besides, due to low threshold voltage and extremely fast switching transients, a negative off voltage level may be needed. Infineon's GaN EiceDRIVER™ solves these issues with very low effort. The two output stages shown below enable a zero off 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.

• Dedicated gate driver ICs for Infineon's high voltage GaN power switches (CoolGaN™, X-GaN™)
• Single output supply voltage (typ. 8 V, floating)
• Switching behavior independent of duty-cycle (2off voltage levels)
• Differential concept to ensure negative gate drive voltage under any condition
• Fast input-to-output propagation (37 ns) with excellent stability (+7/-6ns)
• Galvanic input-to-output isolation based on coreless transformer (CT) technology
• Common mode transient immunity (CMTI) >, 200 V/ns
