7.3.2 Out-of-Range Detection

The INA303 detects when negative currents are out-of-range by setting a voltage at the LIMIT2 pin that is less than the applied reference voltage. The limit voltage is set with an external resistor or externally driven by a voltage source or digital-to-analog converter (DAC); see the Setting Alert Thresholds section for additional information. A typical application using the INA303 to detect negative overcurrent conditions is illustrated in the Typical Application section.
