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. A synschronous enable pin is used to

enable the low-side driver. When disabled, the OUT_Lis logic

low.

The Si9913 is available in both standard and lead (Pb)-free 8-pin

SOIC packages for operation over the industrial operation range

(−40_C to 85_C).
