Working Principle

The XC6122D544ER-G uses a combination of 3 different protection methods i.e. overvoltage protection, over-current protection, and short-circuit protection. The device has a voltage monitoring circuit with some op-amps, which justifies an interfering voltage by comparison with a reference voltage. This differential voltage is compared against a certain threshold set by a reference voltage, and result in a trigger signal for the circuit to shut off power when voltage levels are exceeded. Over-current protection is done by measuring the current flowing through the power supply and triggering the circuit to shut off if the current exceeds a certain limit. Short-circuit protection is done by measuring the voltage differential and comparing it to a set threshold so that power can be cut off in the event of a short circuit.
