General Description

The MAX5915/MAX5915A/MAX5916/MAX5916A dual PCI 2.2 hot-swap controllers allow for safe insertion and removal of two PCI cards into live PCI slots or backplanes by limiting the inrush current at startup. After startup, these devices provide protection against short-circuit, overcurrent, and undervoltage conditions.
