MIC2342/2342R

Dual-Slot PCI Express^®Hot-Plug

Controller

General Description

Features

The MIC2342 is a dual-slot power controller supporting the

power distribution requirements for Peripheral Component

Interconnect Express (PCI Express^®) Hot-Plug compliant

systems. The MIC2342 provides complete power control

support for two PCI Express slots, including the 3.3VAUX

defined by the PCI Express standards. Support for the

12V, 3.3V, and 3.3VAUX supplies includes programmable

gate voltage slew-rate control, voltage supervision,

programmable current limit, and circuit breaker functions.

These features provide comprehensive system protection

and fault isolation. Additionally, in the event of an

overcurrent fault on 3.3VAUX that “trips” the circuit breaker

to cause the 3.3VAUX output to shut down, the MAIN

outputs (3.3V and 12V) for the affected 3.3VAUX slot, A or

B, will also be shut down. The MIC2341 controller

provides truly independent output operation for MAIN and

AUX.

• Supports two independent PCI Express slots

• MAIN & AUX outputs are inter-dependent during AUX

overcurrent conditions

• 12V, 3.3V, and 3.3VAUX supplies supported per PCI

Express Specification v1.0a, v.2.0

• Integrated Power MOSFETS for 3.3VAUX rails

• Standby Operation for Wake-on-LAN applications with

low backfeed on Main +12V and +3.3V rails

• Electronic circuit breakers for each supply per slot

- Programmable gate voltage slew-rate control

- Active current regulation controls inrush current

• High accuracy Primary and Secondary Circuit Breaker

Current-limit Thresholds

• Dual-level, dual-speed fault detection for fast response

without nuisance tripping

Data sheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

• User-programmable Primary Overcurrent Detector

• /PWRGD and Delayed /PWRGD (164 ms) Signal

Outputs per slot

• Separate /FAULT output signals for MAIN and AUX

rails for each slot

• Global Systems Power-is-Good Output

• Both slots thermally isolated

• Internally Debounced Plug-in Card Retention Switch

Inputs per slot.

Applications

• PCI Express v1.0a, v2.0 hot-plug power control
