eFuses

eFuses (electronic fuses) work by sensing current by measuring the voltage across a known resistor. It will break current flow with a field-effect transistor if the current surpasses a pre-set value.

Allows flexibility of setting critical value, choosing to use auto-retry or latch-off modes
Can function at lower current and voltage values relative to thermal fuses
Some provide reverse current protection, overvoltage protection, and reverse polarity protection.

Usually used in conjunction with thermal fuses. eFuses are used locally, and thermal fuses are used for system-level shut-offs.

When picking fuses, consider:

current level at which fuse acts
if current level is fixed or set by external resistor

Electronic fuses can be found at DigiKey and other stores
