MIC2591B
Dual-Slot PCI Express Hot-Plug Controller
General Description
The MIC2591B is a dual-slot power controller supporting the
power distribution requirements for Peripheral Component
Interconnect Express (PCI Express) Hot-Plug compliant
systems incorporating the Intelligent Platform Management
Interface (IPMI) Specication v1.0. The MIC2591B provides
complete power control support for two PCI Express slots,
including the 3.3VAUX dened by the PCI Express standards.
Support for 12V, 3.3V, and 3.3VAUX supplies is provided
including programmable constant-current inrush limiting,
voltage supervision, programmable current limit, and circuit
breaker functions. These features provide comprehensive
system protection and fault isolation. The MIC2591B also
incorporates an SMBus interface via which complete status
of each slot is provided. Data such as voltage and current
from each supply of each slot can be obtained for IPMI sensor
records in addition to the power status of each slot.
All support documentation can be found on Micrel’s web site
at www.micrel.com.
