Working Principles

The MIC4423CN is a high-speed, high-current low-side gate driver IC. It is designed to drive power MOSFETs and IGBTs in various applications. The input control signal (IN) determines the output state of the low-side gate driver (LO). When the input signal is high, the LO output is driven high, turning on the connected power device. Conversely, when the input signal is low, the LO output is driven low, turning off the power device.

The MIC4423CN also features built-in protection mechanisms such as short-circuit protection, undervoltage lockout (UVLO), and thermal shutdown. These protections ensure safe and reliable operation of the power devices.
