Rad Hard GaN Drivers
The space market has been driving towards more efficient power management solutions. Part of the drive includes the use of Gallium Nitride Field Effect Transistors (GaN FETs) for power conversion. GaN FETs have higher power conversion efficiency and have more natural immunity to radiation, due to them being wide-bandgap semiconductors. Equally important is the use of the correct driver that will allow reliable operation and maximize the benefits of the GaN FETs. Some of the key driver requirements are: a well-regulated gate drive voltage; high source/sink current capability and a split driver output stage.

Rad Hard GaN FETs
Wide band gap semiconductor technologies such as Gallim Nitride Field Effect Transistors (GaN FETs) have been gaining interest for power management and conversion in space applications. These devices feature higher breakdown voltage, lower RDS(ON) and very low gate charge enabling power management systems to operate at higher switching frequencies while still achieving higher efficiency and a smaller solution footprint. There is an additional benefit from GaN devices that make them attractive to the space market. These devices are inherently immune to total ionizing dose radiation.

Field Effect Rectifiers
ST field-effect rectifier diodes (FERD) help improve designs with new versions focusing on trade-off upgrades. Field-effect rectifier diodes belong to our STPOWER family. The design of the FERDs has allowed both a decrease in the voltage drop and a decrease in the leakage current temperature coefficient. As a result, the runaway safety margin is improved and maybe beyond the typical safety margin of Schottky barrier diodes.
