8.2
There is a current sense signal available at pin IS which provides a current proportional to the load current of one
selected channel. The selection is done by a multiplexer which is configured via SPI.
Current Sense Signal
The current sense signal (ratio
is connected to the current sense pin. It is recommended to use resistors 2.5 kΩ <
3.3 kΩ.
