SLUA963B June 2020 – October 2022 UCC21710-Q1 , UCC21732-Q1 , UCC5870-Q1
The UCC21732-Q1 is shown in Figure 3-1 along with the various monitoring and protection blocks required in the inverter system. Four categories are used to describe the various blocks: Self-Test, Diagnostics, Protection and Driver Function. Self-Test blocks signify the circuits used to ensure another critical block is functioning properly. The Diagnostic blocks are used to feed back critical information to the MCU to determine monitor the power stage performance and/or behavior. The Protection blocks are used to prevent IGBT failure. Finally the Driver Function blocks include the basic gate driver function.
