MIC2592B-3BTQ规格书详情
General Description
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 defi ned by the PCI Express standards. 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 MIC2592B also incorporates an SMBus interface via which complete status of each slot is provided.
Features
• 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 Specifi cation 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
• 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.
