Power Controller Targets PCI Hot-Plug Apps

The newest member of the MIC259x family of hot-swap, power-control ICs, the MIC2593, relies on an SMBus interface for power control chores while supporting a variety of PCI hot-plug standards. In a 48-pin TQFP, the five-rail-by-dual-slot controller accommodates all system voltages common to PCI v2.3 and PCI-X 1.0b, including the +3.3V auxiliary voltage. In addition, it provides all major power control functions for dual-slot PCI-X 2.0 applications. The device integrates circuitry for controlling external MOSFETs for high-current +5V and +3.3V rails, as well as all control circuitry, current sense, and power MOSFETs for +12V, -12V, and +3.3V auxiliary rails. Price is $6.10 each/1,000. For more details, call Carolyn Lajoie at MICREL SEMICONDUCTOR, San Jose, CA. (510) 476-5963.
