Current sense and diagnostic
The current sense pin performs a double function (see
diagnostic):
●
●
A logic high-level on CS_DIS pin sets at the same time all the current sense pins of the
devices 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.
