Product Overview

The LTC2975IUP#PBF is a 4-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. 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. Supervisory functions include over and under current, voltage and temperature threshold limits for four power supply output channels as well as over and under voltage threshold limits for a single power supply input channel. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors four output voltages, four output currents, four external temperatures, input voltage and current and die temperature.
  • Supported by LTpowerPlay™ GUI
  • Margin or trim supplies to within 0.25% of target
  • Monitor input current (±1%) and accumulate energy
  • Fast OV/UV and OC supervisors per channel
  • Coordinate sequencing and fault management across multiple LTC PSM devices
  • Automatic fault logging to internal EEPROM
  • Operate autonomously without additional software
  • External temperature and input voltage supervisors
  • I2C/SMBus serial interface
