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) Specification v1.0.

Key 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. Features.
  • Supports two independent PCI Express slots.
  • SMBus interface for slot power contr.
