Introduction

DOS4427 is power switch driver. It has a matching rise and fall time when charging and discharging the gate of the power switch. DOS4427 has high latch resistance under all conditions in its rated power and voltage range. When noise spikes of up to 5V (either polarity) occur on the ground pin, the DOS4427 is not damaged. DOS4427 can accept reverse currents up to 500 mA to force back its output without damage or logic confusion. All ports are fully protected by up to 2.0 kV electrostatic discharge (ESD).
