AAT4601 General Description


The AAT4601 SmartSwitch™ is part of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. It is a 1.5A Current Limited P-channel MOSFET power switch designed for high-side load-switching applications.This switch operates with inputs ranging from 2.7V to 5.5V, making it ideal for both 3V and 5V systems.An integrated current-limiting circuit protects the input supply against large changes in load current which could cause the supply to fall out of regulation. The AAT4601 has protection from thermal overload which limits power dissipation and junction
temperatures. The maximum current limit level is 1.5A; the actual threshold is programmed with a resistor from the SET pin to ground. The quiescent supply current is typically 12A. In shutdown mode, the supply current decreases to less than 1A.

The AAT4601 is available in 8-pin SOP or TSSOP specified over -40 to 85
