AAT4680 Datasheet | Advanced Analogic Technologies

Electronic Resettable Fuse 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 bees a constant current source equal to the current limit. If the current limit condition persists long enough to heat the MOSFET to an extreme temperature, the device will thermal...
