Smart Power PlugTM
Penta-Power Sequence Controller with Hot Swap
APPLICATIONS · -48V Hot Swap Power Backplane/Distribution Central Office, Ethernet for VOIP · Card Insertion Detection · Power Sequencing DC-DC/Power Bricks · IP Phone Applications · Databus Power Interfacing · Custom Industrial Power Backplanes · Distributed Power Systems DESCRIPTION The X80000 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 DCDC 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).

X80000/X80001 Preliminary Information
DESCRIPTION (Continued) The hot swap controller allows a board to be safely inserted and removed from a live backplane without turning off the main power supply. The X80000 family of devices offers a modular, power distribution approach by providig flexibility to solve the hotswap and power sequencing issues for insertion, operations, and extraction. Hardshort Detection and Retry with Delay, Noise filtering, Insertion Overcurrent Bypass, and Gate Current selection are some of the programmable features of the device. During insertion, the gate of an external power MOSFET is clamped low to suppress contact bounce. The under-voltage/ over-voltage circuits and the power on reset circuitry suppress the gate turn on until the mechanical bounce has ended. The X80000 turns on the gate with a user set slew rate to limit the inrush current and incorporates an electronic circuit breaker set by a sense resistor. After the load is successfully charged, the PWRGD signal is asserted; indicating that the device is ready to power sequence the DC-DC power bricks.
