Overcurrent Protection Using the Integrated Op Amps on AVR DB
Johan Vaarlid and Martin Mostad
This application note describes how to use the Analog Signal Conditioning (OPAMP), Analog Comparator (AC), the Event System (EVSYS), Configurable Custom Logic (CCL), and Timer/Counter Type D (TCD) to detect overcurrent events and core independently shut down the load.
In the example in the application note, a fan motor is used as the load.
