MIC2593数据手册集成电路（IC）的热插拔控制器规格书PDF

描述 Description

The MIC2593 is a power controller supporting power distribution requirements for Peripheral Component Interconnect hot plug systems compliant to PCI v2.3 and PCI-X 1.0b. TheMIC2593 provides complete power control support for two PCI slots, including the 3.3VAUX defined by the PCI v2.3 specification. Support for +5V, +3.3V, +12V, and -12V supplies is provided and includes programmable current limit, voltage supervision, fault reporting, and circuit breaker functions which provide fault isolation. The MIC2593 also incorporates an SMBus interface that provides complete status and control of power within each slot.

特性 Features

·Supports two completely independent PCI slots:·Compliant to PCI v2.3 and PCI-X 1.0b power control requirements
·Provides all major power control functions for two independent PCI-X 2.0 slots

·Five voltage supplies supported: +12V, -12V, +5V,+3.3V, and +3.3VAUX·Integrated gate driver circuits, current sense, and power MOSFETs for 3.3VAUX, +12V, and -12V
·High-side +5V and +3.3V gate driver circuits for external N-Channel MOSFETs

·Overcurrent protection with adjustable timeout eliminates false tripping of circuit breakers
·Dual-level, dual-speed overcurrent detection circuitry for quick fault response without nuisance tripping
·Slot power control with \"Power-is-Good\" and Fault status reporting·Via software over an SMBus interface or
·Via dedicated hardware input/output lines: Hot Plug Interface (HPI)

·Complete thermal isolation between circuitry for Slot A and Slot B
·One General Purpose Input (GPI) pin per slot for mechanical switch or plug-in card retention/removal input
