MIC2592B  
Dual-Slot PCI Express Hot-Plug Controller  
General Description  
Features  
The MIC2592B is a dual-slot power controller supporting the  
power distribution requirements for Peripheral Component  
Interconnect Express (PCI Express) Hot-Plug compliant  
systems. The MIC2592B provides complete power control  
support for two PCI Express slots, including the 3.3VAUX  
defined by the PCI Express standards. Support for 12V, 3.3V,  
and 3.3VAUX supplies is provided including programmable  
constant-current inrush limiting, voltage supervision, pro-  
grammable current limit, and circuit breaker functions. These  
features provide comprehensive system protection and fault  
isolation.TheMIC2592BalsoincorporatesanSMBusinterface  
via which complete status of each slot is provided.  
• 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.  
• 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.
