MIC2593 Overview
The MIC2593 is a power controller supporting power distribution requirements for Peripheral ponent Interconnect hot plug systems pliant to PCI v2.3 and PCI-X 1.0b. The MIC2593 provides plete power control support for two PCI slots, including the 3.3VAUX defined by the PCI v2.3 specification. Support for +5V, +3.3V, +12V, and 12V supplies is provided and includes programmable current limit, voltage supervision, fault...
MIC2593 Key Features
- Supports two pletely independent PCI slots
