19-0856; Rev 0; 7/07 KIT ATION EVALU E L B A AVAIL Quad PCI Express, Hot-Plug Controllers General Description The MAX5959/MAX5960 quad hot-plug controllers are designed for PCI Express® (PCIe) applications.
These devices provide hot-plug control for the main 12V, 3.
3V, and 3.
3V auxiliary supplies of four PCIe slots.
The MAX5959/MAX5960s’ logic inputs/outputs allow interfacing directly with the system hot-plug management controller or through an SMBus™ with an external I/O expander such as the MAX7313.
An integrated debounced attention switch and present-detect signals simplify system design.
The MAX5959/MAX5960 drive eight external n-channel MOSFETs to control the 12V and 3.
3V main outputs...
