Description

The MIC4420CN is an electronic component model belonging to the gate drivers category. It is a tough, efficient, and easy to use MOSFET driver. The MIC4420CN is a non-inverting driver, while the MIC4429CN and MIC429CN are inverting drivers. These drivers are capable of delivering a peak output current of 6A and have an improved safe operating margin. They can drive large MOSFETs without the need for external speed-up capacitors or resistor networks. The input voltage can range from 2.4V to VS, and the driver can tolerate a negative swing of up to 5V without damage. Additional protection circuits are incorporated to safeguard against electrostatic discharge.
