The X80000 is a smart power plug with penta-power sequence controller and hot swap function. It contains three major functions: a power communications controller, a power sequencing controller, and a hotswap controller. The power communications controller allows smart power supply control via the backplane using the SMBus protocol. The system can check for voltage, current, and manufacturing ID compliance before board insertion. The power distribution network can monitor the status of the negative voltage supply, DC voltage supplies, and hardshort events by accessing the Fault Detection Register and General Purpose EEPROM of the device. Each device has a unique slave address for identification. The power sequencer controller time sequences up to five DC-DC modules. The X80000 allows for various hardwired configurations, either parallel or relay sequencing modes. The power good, enable and voltage good signals provide for flexible DC-DC timing configurations. Each voltage enable signal has a programmable delay. In addition, the voltage good signals can be monitored remotely via the fault detection register (thru the SMBus). The hot
The document describes the Intersil X80000 family of devices, specifically models X80000 and X80001. These chips function as a Smart Power Plug™ Penta-Power Sequence Controller with Hot Swap capabilities. They integrate three major functions: a power communications controller using SMBus protocol, a power sequencing controller for up to five DC-DC modules, and a hot swap controller allowing safe board insertion/removal from live backplanes.
