Unfortunately, there is no such command currently supported by LTM4681.
To get the total output current you would need to read the current of each channel and add them up.
To make sure that the voltages each channel are set the same, you can use the device global address or rail address.
In this specific case you can use the global address because all four channels of…
The factory default NVM (non volatile memory) of LTM4681 is as follows:
>MFR_CONFIG_ALL [6] =0b (Respect resistor configuration pins)
>ON_OFF_CONFIG command: 0x1E (Device requires both RUN pin and…
