8.1 Application Information

The INA381 is designed to enable easy configuration for detecting overcurrent conditions in an application. This device is individually targeted towards unidirectional overcurrent detection of a single threshold. However, this device can also be paired with additional devices and circuitry to create more complex monitoring functional blocks.
