Smart Power Plug
Penta-Power
Sequence Controller with Hot Swap
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
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 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 providing 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
undervoltage/overvoltage 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.
