The ISL6112 targets the PCI-Express add-in card hot plug application. Together with two each of N-Channel and P-Channel MOSFETs, four current sense resistors and several external passive components the ISL6112 provides a compliant hot plug power control solution to any combination of two PCI-Express X1, X4, X8 or X16 slots.

Features

• Supports Two Independent PCI Express Slots
