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 the

driver. 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

(?40C to 85C).
