SI9912 Datasheet (Vishay Siliconix) - Half-Bridge MOSFET Driver for Switching Power Supplies

SI9912, Half-Bridge MOSFET Driver for Switching Power Supplies

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 sw
