I'm looking at modifying the EVK design for a particular application, and had some questions:
* Is the Q2 protection circuitry needed for operation, or is it just for extra protection?
* Is the VDRIVE_SENSE signal going into the IC actively used for operation, or is it just there for diagnostic purposes? (ie. what would happen to the transmitter if it was set to 0V?)
* Is there a reason to measure both VRAIL_SENSE and VRAILA_SENSE when INPUT_CURRENT is already being measured?
* What particular specifications are needed for the half-bridge inverters currently provided by the HIP2103 and HIP2106?
