FRDMGD3160XM3EVM half-bridge evaluation board

Figure 2. Connecting FRDM-KL25Z, GD31xx half-bridge EVB and translator board

4.4.1 Low-voltage logic and control connector

Low-voltage domain is 15 V VSUP domain that interfaces with the MCU and GD3160

control registers through the 24-pin connector interface.
Low-side driver and high-side driver domains are driver control interfaces to XM3 SiC

module single phase connections and test points.
