General Description
The MAX5915/MAX5916 dual PCI 2.2 hot-swap con-
trollers 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 short-
circuit, overcurrent, and undervoltage conditions.
The MAX5915/MAX5916 provide independent power
controls for +3.3V, +5V,
±
12V, and +3.3V auxiliary sup-
plies 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 out-
puts. The MAX5915/MAX5916 use internal charge
pumps to activate the gates of the internal FETs control-
ling 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 MAX5915/MAX5916 to monitor two PCI
card slots.
The MAX5915 offers latched fault protection and the
MAX5916 offers autorestart fault protection. The
devices are available in the low-profile 28-pin TSSOP
package and are specified over the -40
°
C to +85
