High-side

• if ground line cannot be cut (return to neutral by chassis)

• if multiple outputs power supply (all currents are combined in Gnd line)

• if the application is sensitive to RF disturbances

and requires ground line continuity

ST solution: TSC series

Low side

• no need for high voltage silicon technology

• more accurate measurement
