12V/100A Hot Swap Design for Server Farms
Dan Eddleman As data centers servicing the cloud grow in speed and capacity, backplane supplies
are called on to deliver currents that push the performance boundaries of Hot Swap
components. Hot Swap solutions allow boards to be inserted and removed from a live
backplane without disturbing the power distributed to other boards. A typical Hot Swap
solution uses a series MOSFET to manage the flow of power between the backplane and
the boardвЂ”preventing glitches and faults from disrupting power to the rest of the system.
The challenges of designing robust Hot
Swap solutions multiply with increasing
current demands. With load currents at
100A, simply determining power dissipation requirements is no longer sufficient.
Designers must pay careful attention to
the MOSFET safe operating area (SOA) and
understand Kelvin current sensing techniques for multiple sense resistors. This
article shows how to address these issues
using the example of a 12V/100A solution
based on the LTC4218 Hot Swap controller. resistance is low during start-up (such as
might occur during an output short-circuit
fault), the LTC4218 detects this condition and turns off the series MOSFET.
During start-up, the circuitвЂ™s current
limit threshold is reduced by pulling
the LTC4218вЂ™s ISET pin low through R4
until the PG signal transitions high. R4вЂ™s RSENSE RESISTOR ARRAY …
