With the addition of two discrete power MOSFETs and a few passive components, the ISL6111 provides power control for the four legacy supplies (-12V, +12V, +5V, +3.3V) to a PCI or PCI-X slot. This IC integrates the +12V and -12V current sensing and regulation switches. On the 25W capable 3.3V and 5V rails, current regulation (CR) protection is provided by sensing the voltage across external current-sense resistors and modulation of the gate voltage bias on the external N-channel power MOSFETs. During initial power-up of the +12V bias supply, the ENABLE (EN), Power Good (PG), fault monitoring and reporting function...
