  • Power module with integrated surge voltage limiting element
    Patent number: 11349303
    Abstract: One or more embodiments provide a power module that includes a high-side power transistor; a low-side power transistor coupled to the high-side power transistor, the low-side power transistor including a first load path terminal through which a load current enters the low-side power transistor and a second load path terminal through which the load current exits the low-side power transistor; a gate driver integrated circuit (IC) configured to drive the high-side power transistor and/or the low-side power transistor; a leadframe having a low-side voltage pin configured to be coupled to a low-side voltage source; a surge voltage limiting element coupled between the second load path terminal of the low-side power transistor and the low-side voltage pin; and a module package, where the high-side power transistor, the low-side power transistor, the gate driver IC, the leadframe, and the surge voltage limiting element are encapsulated in the module package.
    Type: Grant
