Working Principles

The LM5104M is a high-voltage gate driver IC designed to efficiently drive power MOSFETs and IGBTs in various applications. It utilizes a bootstrap diode to generate the necessary high-side gate drive voltage, eliminating the need for an external isolated power supply. The adaptive shoot-through protection prevents both high-side and low-side MOSFETs from conducting simultaneously, reducing power losses and enhancing system reliability. The programmable dead-time control allows for precise timing between the turn-off of one switch and the turn-on of the other, minimizing the risk of shoot-through current. These features, combined with overcurrent and thermal shutdown protection, make the LM5104M a reliable and efficient choice for power management applications.
