HIP1011 带电插拔PCI控制器的功能及应用The HIP1011 was the first device designed to be fullycompatible with the PCI Hot Plug specification. This devicefacilitates “HOT PLUGGING”, the removal or insertion of PCIcompliant cards without the need to power down the servervoltage bus. The HIP1011 controls all four (-12V, +12V, +3.3V,+5V) supplies found in PCI applications, monitoring andprotecting against over current (OC) and under voltage (UV)conditions. Reference the HIP1011 data sheet (4311) and thePCI Hot Plug specification available from www.pcisig.com.Figure 2 illustrates the typical implementation of theHIP1011. Additional components for optimizing performancein particular applications, ambient electrical noise levels ordesired features will be necessary.The ease of implementation of the HIP1011 Hot PlugSolution (HIP1011 and as few as 2 N-Channel MOSFETslike the ITF86130 UltraFET) is complemented by the smallPCB foot print necessary, since both are available in 0.150inch SOICs. The typical application requires only 1.1 sq.inches of PCB board space (see Figure 1).
