This application is similar to the low side sensing discussed
above, except in this application the common mode voltage

on the shunt drops below ground when the driver is switched
off. Because the common mode voltage range of
the LMP8601/LMP8601Q extends below the negative rail,
the LMP8601/LMP8601Q is also very well suited for this ap-
plication.
