 Gallium nitride (GaN) is a next-generation semiconductor technology that runs up to 20x faster than legacy silicon and enables up to 3x more power and 3x faster charging in half the size and weight. Navitas’ GaNFast™ power ICs integrate GaN power and drive plus protection and control to deliver simple, small, fast and efficient performance.

GaNSense technology integrates real-time, accurate and fast sensing of system parameters including current and temperature. This technology enables a patent-pending loss-less current-sensing capability, which improves energy savings by up to an additional 10% compared to prior generations, as well as further reducing external component count and shrinking system footprints. In addition, if the GaN IC identifies a potentially dangerous system condition, the IC is designed to transition rapidly to a cycle-by-cycle sleep-state, protecting both the device and the surrounding system. GaNSense also integrates an autonomous standby-power feature which automatically reduces standby power consumption when the GaN IC is in idle-mode, helping to further reduce power consumptions, which is especially important to the growing list of customers aggressively pursuing their own environmental initiatives.

With the industry’s tightest current-measurement accuracy and GaNFast response time, GaNSense technology means reducing dangerous over-current spikes by 50% and reducing time in the ‘danger zone’ by 50% compared to previous best-in-class solutions. GaNFast monolithic integration delivers dependable, glitch-free operation with no ‘ringing’, for improved system reliability.

“From detection to protection in only 30 ns, GaNSense technology is 600% faster than discrete GaN implementations,” said Dan Kinzer, COO / CTO and co-founder of Navitas. “This next generation from Navitas provides a highly-accurate and effective defense against potential system failure modes. Couple that with immunity to transient voltages up to 800V and tight gate waveform control and voltage regulation, only possible with our proprietary process design kit, and you have a new standard in reliability, robustness and performance for power semiconductors.”

The new family of GaN power ICs with GaNSense technology spans 10 products, which all have the core, critical GaNFast integration of GaN power, GaN drive, control and protection. All are rated at 650V/800V with 2kV ESD protection, and RDS(ON) ranging from 120 to 450 mOhms in 5×6 and 6×8 mm PQFN packaging… with the GaNSense protection circuits and loss-less current-sensing. This family of 3rd generation GaN ICs is optimized for modern power conversion topologies including high-frequency quasi-resonant (HFQR) flyback, active-clamp flyback (ACF) and PFC boost, which are popular to deliver the fastest, most efficient …….
