MAX34565 Product Details

12V Hot-Plug Switch In TDFN Package 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
