The AAT4702 SmartSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. This device integrates a high side P-channelMOSFET current limiting load switch with a nanopower low dropout (LDO) linear voltage regulator, making the AAT4702 ideal for use in load current protected applications that also require a system power supply. The load switch operates with input voltages ranging from 2.4V to 5.5V, making it ideal for 2.5V, 3V, and 5V systems. A fault flag is provided to alert the system to an overcurrent event. The fault flag has a 5ms blanking time to prevent from reporting false events such as inrush currents during system startup.
