Overvoltage Protection ICs

Overvoltage protection ICs prevent external overvoltage (or undervoltage) peaks from damaging circuitry.
They are commonly implemented on the power charging patch of portable devices to prevent USB or AC charger power failure.
SG Micro's ICs offer the advantage of very precise voltage thresholds, so that the protection is activated accurately, and without fail.
