Working Principles

The LM5112MYX/NOPB is a high-speed gate driver IC designed to efficiently drive high-side and low-side N-channel MOSFETs in half-bridge or full-bridge configurations. It operates by providing the necessary gate drive voltages to the MOSFETs, enabling them to switch on and off rapidly. The adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously, avoiding short circuits. The integrated bootstrap diode simplifies the circuit design by eliminating the need for an external diode.
