Board power-up and input connection

The following image shows how to supply MASTERGAN4, how to provide LIN and HIN inputs and set the

programmable deadtime generator.

The LIN, HIN inputs can be supplied from the on-board deadtime generator or directly from an external generator

(as DSP/MCU) with the following settings:

The pin is connected to HIN pin of MASTERGAN4: the pin can be

used either to monitor the output of the deadtime generator or to force

the input to MASTERGAN4 according to the status of R4 (see table 2)
