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