The AAT4684 OVPSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. It is a P-channel MOSFET power switch with preciseover-voltage protection control, designed to protect low-voltage systems against high-voltage faults up to +28V. If the input voltage exceeds the programmed over-voltage threshold, the P-channel MOSFET switch will be turned off to prevent damage to the output load circuits. The AAT4684 is available with an internally programmed over-voltage trip point or as an adjustable version programmed by two external resistors.
