1 / 10 page  SmartSwitch™ General Description The AAT4680 electronic resettable fuse is a mem- ber of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. 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 cur- rent 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 cycle off and on until the current limit condition is removed. An open drain FAULT flag signals an over-current or over-temperature condi- tion. Quiescent current is typically a low 10µA. The AAT4680 is available in a Pb-free, 5-pin SOT23 package and is specified over the -40°C to +85°C temperature range.
