8.2 Typical Application

The INA30x-Q1 are designed to be easily configured for detecting multiple out-of-range current conditions in an application. These devices are capable of monitoring and providing overcurrent detection of bidirectional currents. By using the REF pin of the INA303-Q1, both positive and negative overcurrent events can be detected.
