Product Overview

The LTC2978ACUP#PBF is a 8-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 overvoltage and undervoltage threshold limits for eight power supply output channels and one power supply input channel, as well as over and under temperature limits. 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 blackbox EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors eight output voltages, one input voltage and die temperature. In addition, odd numbered channels can be configured to measure the voltage across a current sense resistor.
  • Supported by LTpowerPlay™ GUI
  • Margin or trim supplies to 0.25% accuracy
  • Coordinate sequencing and fault management across multiple chips
  • Operate autonomously without additional software
  • Internal temperature and input voltage supervisors
  • Accurate monitoring of eight output voltages, input voltage and internal die temperature
  • I²C/SMBus serial interface
  • Programmable watchdog timer
  • 100% Pin-compatible upgrade to the LTC2978
  • Green product and no Sb/Br
