Working Principles

The TC4426AVPA is designed to drive MOSFETs and IGBTs in various applications. It operates by receiving an input control signal (IN) which determines the state of the low-side output (LO). The high-side output (HO) is controlled using a bootstrap capacitor (VB) and a separate supply voltage (VS). When the input signal transitions, the driver quickly switches the outputs, allowing efficient power device operation.

The TC4426AVPA is commonly used in the following applications:

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