10.1 Application Information
This typical connection diagram highlights the required external components and system-level connections for
proper operation of the device. This configuration can be realized using the Evaluation Module (EVM) of the
device. This flexible module allows full evaluation of the device in all available modes of operation. Also see the
DRV632 product page for information on ordering the EVM.
