Description: The ISL6161 is a hot swap dual supply power distribution controller that can be used in PCI Express (PCIe) applications. Two external N-channel MOSFETs are driven to distribute and control power while providing load fault isolation. At turn-on, the gate of each external N-channel MOSFET is charged with a 10μA current source. Capacitors on each gate create a programmable ramp (soft turn-on) to control in-rush currents. A built-in charge pump supplies the gate drive for the 12V supply N-channel MOSFET switch.
