Unique MOSFET/IGBT drivers and their applications in future power electronic systems

Advances and breakthroughs continue in MOSFET and IGBT device technology and control strategies to accomplish goals of efficiency and compactness. It is imperative then to have matched MOSFET/ IGBT driver technology and techniques for reaping all the benefits. This paper describes three unique power management ICs: a 30 amp driver, a 45 MHz driver and a 6 amp high/low side phase-leg driver. These drivers deliver the required di/dt, minimize switching and conduction losses, enhance dv/dt immunity, offer UV, OV, features and OL/DESAT protections with soft turn-off using a novel ENABLE function. Unique circuitry is built-in to avoid cross conduction in the output stage of the driver IC. The paper describes many technical issues in applying these "first of a kind" products in modern day power electronics.
