1 Features

  • Sequence and monitor up to 16 analog rails
  • PWM margining on up to 8 rails
  • Cascade up to 4 devices to sequence up to 64 rails
  • Active trim function allows user to trim output voltage
  • Monitor and respond to OV, UV, time-out, and GPI-triggered faults
  • Flexible sequencing dependencies, delay times, Boolean logic, and GPIO configurations
  • Rail status dependent sequencing, delay times, and LGPO pins for complex sequencing applications
  • Four rail profiles for adaptive voltage identification (AVID) voltage regulator
  • Nonvolatile fault event logging with RTC and timestamping
    • Single-event fault log (100 entries)
    • Black box fault log saves fault information and status of all rails - for the first fault and the last fault before a power down event
  • Continue monitoring rails during configuration activities to maximize up-time
  • Programmable watchdog timer and system reset
  • GPI Controlled Rail Groups
  • SEU mitigation and ECC (single-error correct + double-error detect)
  • PMBus™ 1.2 compliant
  • PMBus security profile Level 0 with custom commands to enable features in security profile Level 2
