IX4427NTR

The IX4427N is a power switch series driver. It features matched rise and fall times when charging and discharging the gates of power switches. It offers high latch resistance under any conditions within its rated power and voltage range. It will not be damaged by noise spikes of up to 5V (either polarity) on the ground pin. It can accept reverse currents of up to 500mA forced back into its outputs without damage or logic upset. All terminals are fully protected against up to 2.0kV ESD. Packaged in an SOIC8, it operates over a temperature range of -40°C to 125°C. The IX4427N is an ultra-high-speed, high-current power chip driver with matched rise and fall times when charging and discharging the gates of power switches. It offers high latch resistance under any conditions within its rated power and voltage range. It will not be damaged by noise spikes of up to 5V (either polarity) on the ground pin. It can accept reverse currents of up to 500mA forced back into its outputs without damage or logic upset. The IX4427N features two independent signal input ports for receiving control signals from the host controller without mutual interference. These two ports are designed with high reliability — even with 500mA reverse currents forced back into the outputs, no damage or logic upset will occur. The signal input ports also have the capability to directly handle voltages down to -10V, ensuring safe operation under large noise waveforms and enhancing device stability. The IX4427N output is inverted relative to the input and can be used to drive either P-type or N-type MOSFETs. Each output port can source or sink peak currents of 2A. Its high-speed, high-current characteristics make it well suited for driving MOSFETs in high-frequency application designs.
