The AAT4601 SmartSwitch is a member ofAnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. It is a 1.8A currentlimited P-channel MOSFET power switch designedfor high-side load switching applications. Thisswitch operates with inputs ranging from 2.7V to5.5V, making it ideal for both 3V and 5V systems.An integrated current-limiting circuit protects theinput supply against large changes in load currentwhich could cause the supply to fall out of regulation.The AAT4601 has protection from thermal
overload which limits power dissipation and junctiontemperatures. The maximum current limit level willguarantee that 1.8A can be delivered to the load;the actual threshold is programmed with a resistorfrom the SET pin to ground. The quiescent supplycurrent is typically 12μA. In shutdown mode, thesupply current decreases to less than 1μA.
