LTC2980IY#PBF

LTC2980 is a 16-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 sixteen power supply output channels and two power supply input channels, 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 black box EEPROM storage of fault status and associated telemetry. It is widely used in application such as computers and network servers, industrial test and measurement, high reliability systems, medical imaging, video etc.

• Manage faults, monitor telemetry and create fault logs, PMBus™ compliant command set
