Digital Gate ICs for Driving and Sensing Power Devices to Achieve Low-Loss, Low-Noise, and Highly Reliable Power Electronic Systems

In order to shift the business of power electronics systems such as power converters using power devices from a sellout type to a subscription type that provides the best service for each user, digital gate 1Cs that drive and sense power devices and are connected to the network will be a key technology. This paper presents several examples of the development of digital gate 1Cs that integrate a sensor, a controller, and a digital gate driver to digitally control gate current in fine time steps on a single chip.
