SI9912 General Description

The Si9912 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 Si9912 comes with an internal break-before-make feature to prevent shoot-through current in the external MOSFETs. A shutdown pin is used to enable thedriver. When disabled, the quiescent current of the driver is less than 5 A.

The Si9912 is available in both standard and lead (Pb)-free, 8-pin SOIC packages for operation over the industrial operation range (−40 to 85).
