Gate Drivers

In power management applications, the gate driver transfers power input from a controller IC to a transistor gate such as a MOSFET. ROHM has developed on-chip transformer processes for compact isolated gate drivers using proprietary microfabrication technology. A broad lineup of isolated gate drivers is available for automotive, industrial, and consumer applications.
