Working Principles

The FAN7393M is designed to provide high voltage gate drive signals to power devices like MOSFETs and IGBTs. It operates by receiving an input control signal (IN) and generating complementary output signals (HO and LO) to drive the high-side and low-side gates of the power device. The integrated bootstrap diode simplifies the high-side gate drive circuitry by utilizing the voltage generated across an external bootstrap capacitor.

The UVLO protection ensures that the driver does not operate below a certain voltage threshold, preventing improper operation during low voltage conditions. The OCP protection monitors the current flowing through the driver and shuts it down if an over-current event occurs, protecting both the driver and the power device.
