MIC2590

The MIC2590B is a power controller supporting power distribution requirements for Peripheral Component Interconnect (PCI) hot plug compliant systems incorporating the Intelligent Platform Management Interface (IPMI). The MIC2590B provides complete power control support for two PCI slots including the 3.3VAUX defined by the PCI 2.2 specification. Support for +5V, +3.3V, +12V and -12V supplies is provided including programmable constant-current inrush limiting, voltage supervision, programmable current limit, fault reporting and circuit breaker functions which provide fault isolation. The MIC2590B also incorporates a SMBus interface in which complete status and control of power within 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 power status of each slot.
