Breakthrough on Over-Voltage Protection GaN IC

Ganpower International (GPI) is pleased to announce a major technical breakthrough: the successful design and tapeout of a power GaN device monolithically integrated with a gate over-voltage protection (patent-pending) circuit. The integrated GaN power device includes an IC module with functionality of over-voltage protection and level shifting and it shall be named OVP-GaN (or over-voltage protected GaN).

We believe the invention holds the key from the silicon world to the GaN kingdom. It serves two purposes: resolving the reliability issue of GaN perceived as causing by an over sensitive gate and offering compatibility with gate voltage (Vg) of existing silicon drivers. Typically Vg ranges from 4.5V to 20V in the silicon world. Our proof of concept on-wafer testing experiment indicates the OVP-GaN runs safely and performs well with Vg up to 30 Volt. Theoretically, it can withstand Vg up to 100V which is the breakdown voltage of the integrated circuit. Conventional GaN can only withstand about seven volts beyond which the forward-bias current of the Schottky gate increases exponentially causing irreversible damages. Effort is underway to package these devices in 650V, 15A and 30A ratings and we expect samples will be made available within weeks. GPI wishes to acknowledge collaboration with and assistance by its joint venture partner Ganpower Semiconductor (Foshan, China) Ltd and Residential Air Conditioner Division, Midea Group (China).
