Innoscience GaN devices that innovate 48V motor drive.
GaN 48V motor drive solution achieving high efficiency, low heat generation, and miniaturization.
GaN 48V motor drive solution achieving high efficiency, low heat generation, and miniaturization.
Innoscience's GaN solution for 48V motor drives significantly improves the losses, heat generation, and frequency limitations associated with traditional Si devices, providing design flexibility to accommodate high output drives in the 1kW class. The unique high-speed switching of GaN allows for a reduction of dead time to 100ns, and even with an increase in frequency (from 20kHz to 40kHz), the increase in losses is limited to just 0.7W, demonstrating a significant advantage compared to the 4.1W increase seen with Si. Additionally, under the same cooling conditions, GaN operates at a temperature 23°C lower than Si, making it easier to reduce the size of heat dissipation components and heat sinks. Furthermore, in an on-package configuration, no heat sink is required when operating below 18A, strongly supporting the demand for lightweight, high-efficiency, and high power density in 48V motor systems such as robots, AGVs/AMRs, power tools, and drones.

basic information
For 48V motor drive applications, we offer solutions that utilize 100V-rated GaN HEMTs/GaN ICs, compatible with 48-60V input. The discrete configuration INNDMD48V25A1 achieves a continuous peak of 25A equivalent / 1kW class using: - INN100EA035A (100V / 35mΩ GaN HEMT) ×6 - INS2003FQ (100V compatible GaN driver IC) ×3. On the other hand, the integrated INNDMD48V22A1 uses ISG3204LA (100V integrated half-bridge GaN) ×3, supporting the 22A class. Both configurations are optimized for 48V motor applications, featuring voltage and current capabilities, and integration levels that enable lower losses and heat generation compared to equivalent Si products, allowing for high power density designs.
