MIC2593

Dual-Slot PCI Hot Plug Controller

General Description

Features

The MIC2593 is a power controller supporting power

distribution requirements for Peripheral Component

Interconnect hot plug systems compliant to PCI v2.3 and

PCI-X 1.0b. TheMIC2593 provides complete power control

support for two PCI slots, including the 3.3V_AUXdefined 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 reporting, and circuit

breaker functions which provide fault isolation. The

MIC2593 also incorporates an SMBus interface that

provides complete status and control of power within each

slot.

• Supports two completely independent PCI slots:

–

Compliant to PCI v2.3 and PCI-X 1.0b power

control requirements

–

Provides all major power control functions for two

independent PCI-X 2.0 slots

• Five voltage supplies supported: +12V, -12V,

+5V,+3.3V, and +3.3V_AUX

–

Integrated gate driver circuits, current sense, and

power MOSFETs for 3.3V_AUX, +12V, and –12V

High-side +5V and +3.3V gate driver circuits for

external N-Channel MOSFETs

• Overcurrent protection with adjustable timeout

Data sheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

eliminates false tripping of circuit breakers

• Dual-level, dual-speed overcurrent detection circuitry

for quick fault response without nuisance tripping

• Slot power control with “Power-is-Good” and Fault

status reporting

–

Via software over an SMBus interface or

Via dedicated hardware input/output lines: Hot

Plug Interface (HPI)

• Complete thermal isolation between circuitry for Slot A

and Slot B

• One General Purpose Input (GPI) pin per slot for

mechanical switch or plug-in card retention/removal

input

Applications

• PCI hot plug power distribution

Ideal Applications:

• Mid- and High-end Server Applications compliant to PCI

v2.3, PCI-X 1.0b, and PCI-X 2.0
