8.2.1.2.1 Overload Recovery With Negative VSENSE

The INA310x is a unidirectional current sense amplifier that is meant to operate with a positive differential input voltage (VSENSE). If negative VSENSE is applied, the device is placed in an overload or saturated condition and requires time to recover after VSENSE returns positive. The required overload recovery time increases with more negative VSENSE.
