Active: In Production.

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.

The MAX5915/MAX5915A/MAX5916/MAX5916A provide independent power controls for +3.3V, +5V, ±12V, and +3.3V auxiliary supplies of two PCI cards. These devices provide intelligent selective thermal shutdown control that shuts down the channel with an overcurrent fault. All devices include internal power MOSFETs for the +12V, -12V, and +3.3V auxiliary outputs. These devices use internal charge pumps to activate the gates of the internal FETs controlling the +3.3V auxiliary supply. Internal FETs and current-sense circuitry regulate the ±12V and the +3.3V auxiliary supplies. Channels A and B operate independently, allowing a single device to monitor two PCI card slots.

The MAX5915/MAX5915A offer latched fault protection and the MAX5916/MAX5916A offer autorestart fault protection. The devices are available in the low-profile 28-pin TSSOP package.
