Figure 3-12 shows the block diagram of the gate driver daughter card inserted onto the main power board. The UCC21530 is the main gate driver driving the SiC MOSFETs of the power stage. Each block will be elaborated in detail in the following sections. For a detailed explanation on the selection of components and functionality of the UCC21530, see the Automotive Dual Channel SiC MOSFET Gate Driver Reference Design with Two Level Turn-off Protection.
