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.
