MAX34565:12V Hot-Plug Switch in TDFN Package

Integrated, Self-Protected Electronic Switch Allows the Safe Insertion and Removal of Equipment Into 12V Backplanes

The MAX34565 is a hot-plug controller for 12V power rails. It is a completely integrated solution including the required power-pass MOSFET device for 12V supplies. During hot-plug, the device controls the supply output voltage ramp (dV/dt) and limits the current at a user-controlled level. The device also limits the output voltage to protect downstream devices from overvoltage events. The MAX34565 is offered in a latchoff version.
