Working Principle of the LM5100CMA/NOPB

The LM5100CMA/NOPB is designed to convert voltage signals into drive current for power transistors. It is a monolithic, high-performance gate driver IC, designed to provide a combination of fast transient response and low power dissipation. The LM5100CMA/NOPB has an integrated bootstrap diode, which eliminates the need for external bootstrap diodes. The LM5100CMA/NOPB has a 100V driving voltage, allowing it to drive broad-base FETs and IGBTs in high voltage applications. When the output of the LM5100CMA/NOPB is low, the current from the power supply is drawn through the driver IC. This results in the gate of the transistor being pulled to the low voltage. When the output of the LM5100CMA/NOPB is high, the current from the power supply is drawn through the diode connected to the driver IC\'s output, resulting in the gate of the transistor being pulled to the high voltage. This process allows for efficient switching of the power transistor.
