Working Principles

The IR2133 operates by receiving logic inputs from a microcontroller or other control circuitry. These inputs control the high-side and low-side gate drivers, which in turn drive the power MOSFETs or IGBTs. The integrated bootstrap diode provides the necessary voltage for the high-side gate driver. The adjustable dead time ensures proper switching between the high-side and low-side devices, preventing shoot-through currents. The fault shutdown feature protects the system by disabling the gate drivers in case of overcurrent or overtemperature conditions.
