Dual PCI 2.2 Hot-Swap Controllers
MAX5915/MAX5916
General Description
The MAX5915/MAX5916 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, the MAX5915/MAX5916 provide protection against shortcircuit, overcurrent, and undervoltage conditions.
The MAX5915/MAX5916 provide independent power controls for +3.3V, +5V, ±12V, and +3.3V auxiliary supplies of two PCI cards. The MAX5915/MAX5916 provide intelligent selective thermal shutdown control that shuts down the channel with an overcurrent fault. Both the MAX5915 and MAX5916 include internal power MOSFETs for the +12V, -12V, and +3.3V auxiliary outputs. The MAX5915/MAX5916 use internal charge pumps to activate the gates of the internal FETs controlling the +3.3V auxiliary supply. Internal FETs and currentsense circuitry regulate the ±12V and the +3.3V auxiliary supplies. Channels A and B...
