This reference design implements a 48V three-phase inverter with smart half-bridge gate drivers for low-voltage servo motors. The design is fully tested at 48V.
The major building blocks of this reference design can be split into six different subsystems:
Figure 2-1 shows the TIDA-010956 block diagram. The host processor to control the motor is not part of this design.
The focus of this design is to test the three-phase power stage, focusing on the gate drivers and the FETs. Functional tests of the in-phase current sensing is also being done. The diagnostic measurements and the shutdown options are not yet fully tested in this design.
