General Description
The AAT4680 Electronic Resettable Fuse is part of
the AnalogicTech Application Specific Power MOS-
FET (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 thresh-
old, 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. If the current limit condi-
tion 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 condition.
Quiescent current is typically a low 10μA.
The AAT4680 is available in a 5
-
pin SOT-23, spec-
ified over a -40 to 85°C temperature range.
