Current sense and diagnostic
The current sense pin performs a double function (see
diagnostic):
A logic level high on CS_DIS pin sets at the same time all the current sense pins of the
device in a high impedance state, thus disabling the current monitoring and diagnostic
detection. This feature allows multiplexing of the microcontroller analog inputs by sharing of
sense resistance and ADC line among different devices.
Current mirror of the load current in normal operation, delivering a current
proportional to the load one according to a known ratio K
