DESCRIPTION
The Si9913 is a dual MOSFET high-speed driver with break-before-make. It is designed to operate in high frequency dc-dc switchmode power supplies. The high-side driver is bootstrapped to handle the high voltage slew rate associated with “floating” high-side gate drivers. Each driver is capable of switching a 3000-pF load with 60-ns propogation delay and 25-ns transition time. The Si9913 comes with internal break-before-make feature to prevent shoot-through current in the external MOSFETs.
