Advanced Analogic Technologies AAT4682
The AAT4682 Dual Electronic Resettable fuse is part of the AnalogicTech Application Specific Power MOSFET (ASPM™) line of products. It has two 1A current limited P-channel MOSFET power devices that remain 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. The AAT4682 is available in a 6 pin SOT-23, specified over a -40 to 85°C temperature range.| Part No. | AAT4682 |

GENERAL DESCRIPTION
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 condition persists long enough to heat the MOSFET to an extreme temperature, both devices will thermal cycle off and on until the current limit condition is removed. Independent open drain FAULT flags signal an over current or over temperature condition. Quiescent current typically is a low 10µA.FEATURES
