Rad Hard Power
Renesas' radiation hardened (rad hard) power products achieve the stringent voltage accuracy required of FPGAs, ASICs, microprocessors, and microcontrollers used in space and harsh environment applications. Our solutions enable regulation accuracy over input voltage, load current variation, switching noise, and large load transients and have proven highly reliable within mixed radiation exposure rates and other harsh environment variants.

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.
