Isolated gate drivers for power density & isolation

An isolation device allows data and power transfer between high- and low-voltage units, while preventing hazardous DC or uncontrolled transient current flowing from the grid. Isolation robustness is realized by integrating the isolator with the high-speed gate driver. Gate drivers are available in basic, functional and reinforced isolation and accept low-power input from a controller IC to produce the appropriate high-current gate drive for a MOSFET, IGBT, SiC or GaN power switch.
