MIC2591B Datasheet Dual-slot Pci Express Hot-plug Controller

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: MIC2591B Dual-Slot PCI Express Hot-Plug Controller .. General.

General Description

The MIC2591B is a dual-slot power controller supporting the power distribution requirements for Peripheral ponent Interconnect Express (PCI Express) Hot-Plug pliant systems incorporating the Intelligent Platform Management Interface (IPMI) Specification v1.0.

The MIC2591B provides plete power control support for two PCI Express slots, including the 3.3VAUX defined 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.

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.
