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.
