4.2 Hardware Connections Overview – DRV83 LAUNCHXL-F280049C
Figure 4-5 shows the major blocks of DRV8316xEVM plugin module that mounts to the J1/J3 and J2/J4 headers
of the LAUNCHXL-F280049C LaunchPad development kit. The DRV8316xEVM is designed for an input supply
from 4.5-V to 35-V and up to 8-A drive current. The DRV8316 includes three integrated half-bridges that can
drive 8-A peak current and can be used in systems implementing sensored, sensorless, or field-oriented control.
The 3.3-V supply to the Hall sensors is derived by the buck converter integrated in the DRV8316.
