Motor Drive ICs for Home Appliance and Industrial
The new GaNSense™ Motor Drive ICs integrate high performance eMode GaN FETs with integrated gate drive, control and protection to achieve unprecedented high-frequency and high efficiency operation. GaNSense motor drive technology is also integrated which enables real-time, accurate sensing of voltage, current and temperature to further improve performance and robustness not achieved by any discrete GaN or discrete silicon device.
High efficiency and integration with full robustness
GaNSense motor drive enables integrated bidirectional loss-less current sensing which eliminates external current sensing
resistors and increases system efficiency. GaNSense motor drive also enables short circuit and over-temperature protection to
increase system robustness. For applications up to 600W.
