MIC2593

Dual-Slot PCI Hot Plug Controller

General Description

Features

TheMIC2593isapowercontrollersupportingpowerdistribu-

tionrequirementsforPeripheralComponentInterconnecthot

plug systems compliant to PCI v2.3 and PCI-X 1.0b. The

MIC2593 provides complete power control support for two

• 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

PCI slots, including the 3.3V

defined by the PCI v2.3

AUX

specification. Support for +5V, +3.3V, +12V, and –12V sup-

plies is provided and includes programmable current limit,

voltage supervision, fault reporting, and circuit breaker func-

tions which provide fault isolation. The MIC2593 also incor-

porates an SMBus interface that provides complete status

and control of power within each slot.

• 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

, +12V, and –12V

AUX

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

external N-Channel MOSFETs

• Overcurrent protection with adjustable timeout elimi-

nates 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
