MIC2591B  
Dual-Slot PCI Express Hot-Plug Controller  
General Description  
Features  
The MIC2591B is a dual-slot power controller supporting the  
power distribution requirements for Peripheral Component  
Interconnect Express (PCI Express) Hot-Plug compliant  
systems incorporating the Intelligent Platform Management  
Interface (IPMI) Specification v1.0. The MIC2591B provides  
complete power control support for two PCI Express slots,  
includingthe3.3VAUXdefinedbythePCIExpressstandards.  
Support for 12V, 3.3V, and 3.3VAUX supplies is provided  
including programmable constant-current inrush limiting,  
voltage supervision, programmable current limit, and circuit  
breaker functions. These features provide comprehensive  
system protection and fault isolation. The MIC2591B also  
incorporates an SMBus interface via which complete status  
of each slot is provided. Data such as voltage and current  
fromeachsupplyofeachslotcanbeobtainedforIPMIsensor  
records in addition to the power status of each slot.  
• Supports two independent PCI Express slots  
• SMBus interface for slot power control and status  
• Voltage-tolerant I/O for compatibility with SMBus 2.0  
systems  
• 12V, 3.3V, and 3.3VAUX supplies supported per PCI  
Express Specification v1.0a  
- Intergrated power MOSFETs for 3.3VAUX rails  
- Standby operation for Wake-on-LAN applications with  
low backfeed on Main +12V and +3.3V rails.  
• On-chip circuitry for data collection of each rail output  
voltage and output current for both slots  
- Integral analog multiplexer and 8-bit ∆Σ ADC  
- Compliant to the Intelligent Platform Management  
Interface (IPMI) Specification v1.0  
- Conversion results available via an SMBus interface  
• Programmable inrush current limiting  
• Active current regulation controls inrush current  
• Electronic circuit breaker for each supply to each slot  
• High accuracies for both circuit breaker trip points and  
nuisance trip prevention timers  
All support documentation can be found on Micrel’s web site  
at www.micrel.com.  
• Dual level fault detection for quick fault response without  
nuisance tripping  
• Thermal isolation between circuitry for Slot A and Slot B  
• Two General Purpose Input pins suitable for interface to  
logic and switches.  
Applications  
• PCI Express v1.0a hot-plug power control
