General Description

The AAT4680 Electronic Resettable Fuse is part of the AnalogicTech Application Specific Power MOSFET (ASPM™) line of products.

It is a 1A current limited P-channel MOSFET power device that remains fully enhanced as long as the input power supply is above an under voltage lockout threshold, and the load is below the current limit setting.

If the load increases above the current limit setting, as is the case during a short circuit, the MOSFET effectively becomes a constant current source equal to the current limit.
