Working Principles

The LM5102MMX/NOPB is a high-speed gate driver designed to control the switching of power MOSFETs and IGBTs in power electronics applications. It utilizes a bootstrap technique to provide the necessary voltage levels for driving the high-side MOSFET or IGBT.

The adaptive shoot-through protection prevents both the high-side and low-side MOSFETs from conducting simultaneously, avoiding damaging cross-conduction. The integrated bootstrap diode simplifies the circuit design by eliminating the need for an external diode.

Thermal shutdown protection ensures that the device shuts down when the temperature exceeds a safe threshold, preventing damage due to overheating. The low quiescent current reduces power consumption during standby or idle periods.

Detailed Application Field Plans

The LM5102MMX/NOPB is commonly used in various power electronics applications, including:

1. Switching Power Supplies
