Analog Devices Inc. LTC2980-24 PMBus Power System Manager

Analog Devices Inc. LTC2980-24 PMBus Power System Manager is used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. The PMBus commands support power supply sequencing, precision point-of-load voltage adjustment, and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances.

  • Manage faults, monitor telemetry, and create fault logs
  • PMBus™ compliant command set
  • Supported by LTpowerPlay® GUI
  • Margin or trim supplies to within 0.25% of the target
  • Fast OV/UV supervisors per channel
  • Coordinate sequencing and fault management across multiple LTC PSM devices
  • Automatic fault logging to internal EEPROM
  • Operate autonomously without additional software
  • Internal temperature and input voltage supervisors
  • Accurate monitoring of 16 output voltages, two input voltages, and internal die temperature
  • I2C/SMBus serial interface
  • Can be powered from 3.3V, or 4.5V to 15V
  • Programmable watchdog timer
  • Available in 144-pin 12mm × 12mm BGA Package

Applications

  • Computers and network servers
  • Industrial test and measurement
