  Power Supply Sequencing Simplified
  Design Note 1037
  Nathan Enger
  Introduction
  Designing a multiple power supply system is challenging. The power supply designer’s workload multiplies
  with each additional supply rail. The designer must
  consider the dynamic environment of coordinated
  power supply sequencing and timing, generating
  power-on reset, monitoring for faults and responding
  appropriately to protect the system. An experienced
  designer recognizes that flexibility is key to successfully navigating the ebb and flow as a project moves
  from prototype to production. The ideal solution
  minimizes the number of hardware and software
  changes during development.
  The ideal multisupply design tool is a single IC that
  resides in a design from beginning to end, requiring no wiring changes through the life cycle of the
  product. It autonomously supervises and sequences
  multiple power rails, cooperating with other ICs to
  seamlessly supervise many power regulators in the
  system, and provides fault and reset management.
  The designer can use powerful PC-based software
  to configure, visualize and debug system behavior in
  real time when connected to an I2C bus. The LTC2937 fits this bill. It is a 6-channel voltage sequencer and high accuracy supervisor with …

  channels has two dedicated comparators
  to accurately monitor over-and undervoltage conditions to within В±0.75%. …
