    Dual-Slot PCI Express Hot-Plug Controller General Description Features 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. The MIC2591B provides
    complete 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. 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. Supports two independent PCI Express slots SMBus interface for slot power control and status Voltage-tolerant I/O for compatibility with SMBus 2.0
