Isolated IGBT Gate Driver

The combined high efficiency and fast switching features of Insulated-Gate Bipolar Transistor (IGBT) make it ideal for high current and fast switching applications. On the other hand, a gate driver is the one that accepts low-current input from a controller and produces a high-current drive input for the gate of a high-power transistor that is usually an IGBT. This reference design is an isolated IGBT gate driver, which utilizes ISO5852S from Texas Instruments. The ISO5852S is a 5.7kVRMS, reinforced isolated, IGBT gate driver with split outputs, OUTH and OUTL, providing 2.5A source and 5A sink currents. Read more
