MIC2341/2341R  
Dual-Slot PCI Express Hot-Plug  
Controller  
General Description  
Features  
The MIC2341 is a dual-slot power controller supporting the  
power distribution requirements for Peripheral Component  
Interconnect Express (PCI Express) Hot-Plug compliant  
systems. The MIC2341 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.  
Supports two independent PCI Express slots  
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  
Data sheets and support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
High accuracy Primary and Secondary Circuit  
Breaker Current-limit Thresholds  
Dual-level, dual-speed fault detection for fast  
response without nuisance tripping  
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
