12V/5V Hot-Plug Switch
General Description
The MAX34561 is a dual, self-contained, hot-plug switch intended to be used on +12V and +5V power rails to limit through current and to control the power-up output-voltage ramp. The device contains two on-board n-channel power MOSFETs that are actively closed-loop controlled to ensure that an adjustable current limit is not exceeded. The maximum allowable current through the device is adjusted by external resistors connected between the LOAD and ILIM pins. The device can control the power-up output-voltage ramp. Capacitors connected to the VRAMP pins set the desired voltage-ramp rate. The output voltages are unconditionally clamped to keep input overvoltage stresses from harming the load.
