The TC4422EPA is an advanced dual power MOSFET driver integrated circuit (IC) manufactured by Microchip Technology Inc. This IC is designed to provide high-speed switching of high current loads with quick rise and fall times, making it ideal for driving power MOSFETs and IGBTs in various applications. Here is an overview of the key features of the TC4422EPA:
1. Dual Output: The TC4422EPA IC consists of two independent output channels, allowing it to drive two MOSFETs simultaneously. This feature makes it suitable for driving half-bridge or full-bridge configurations.
2. High-Speed Switching: With a typical propagation delay of only 25 ns, the TC4422EPA ensures quick response times. This enables it to efficiently control power switches in applications requiring fast switching, such as motor drives and switch-mode power supplies.
3. Wide Input Compatibility: The IC has a wide input voltage range from 4.5V to 18V, making it compatible with various control logic levels, including TTL and CMOS. This versatility simplifies its integration into different circuit designs.
4. Low Shoot-Through Current: The TC4422EPA incorporates a unique circuit design that minimizes shoot-through current during the transition between the on and off states of the power switches. This prevents both MOSFETs from conducting simultaneously, reducing power losses and enhancing efficiency
