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. The 3.3V auxiliary outputs are controlled through 0.2Ω n-channel MOSFETs.
