Working Principles

The MIC4426CN is a power MOSFET and IGBT driver. It receives an input control signal (IN) and generates complementary gate drive signals for the high-side (HO) and low-side (LO) drivers. The bootstrap supply voltage (VS) provides the necessary voltage level for driving the high-side gate. The device incorporates shoot-through protection to prevent both drivers from conducting simultaneously, ensuring safe operation.

Application Field Plans

The MIC4426CN is commonly used in various applications, including:

1. Motor control systems
2. Switching power supplies
3. DC-DC converters
4. Inverters
5. LED lighting systems
