Infineon Technologies CoolGaN™ Drive HB 600V G5 Switches
Infineon Technologies CoolGaN™ Drive HB 600V G5 Switches integrate a half-bridge power stage featuring two 600V enhancement-mode CoolGaN switches with on-resistance options of 140mΩ, 270mΩ, or 500mΩ. These switches include built-in gate drivers and come in a compact 6mm × 8mm TFLGA-27 package. Designed for low-/medium-power applications, these switches are ideal for high-density motor drives and switch-mode power supplies (SMPS), leveraging the superior switching performance of CoolGaN technology. Infineon’s CoolGaN switches feature a robust gate structure that ensures minimal on-resistance when driven by a continuous gate current of just a few milliamps in the “on” state.
Due to GaN’s low threshold voltage and fast switching transients, certain applications require a negative gate drive voltage to enable rapid turn-off and prevent cross-conduction. This is easily implemented using a standard RC interface between the driver and the switch, with only a few external SMD resistors and capacitors needed for adaptation to various power topologies.
The integrated driver, built on Infineon’s SOI technology, delivers exceptional ruggedness and noise immunity while maintaining logic operation at negative gate voltages. A floating channel supports driving the high-side GaN die with an integrated bootstrap configuration.
