Product Overview
LTC2972 is a 2-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 voltage and temperature threshold limits for two 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. It is used in application such as computers and network servers, industrial test and measurement, high reliability systems, video and medical imaging etc.
- PMBus compliant command set
- Supported by LTpowerPlay® GUI
- Total unadjusted error is ±0.25% of reading typical at (TJ = 25°C, VPWR = VIN-SNS = 12V)
- Fast OV/UV supervisors per channel, automatic fault logging to internal EEPROM
- Operate autonomously without additional software, configurable power good output pins
- Coordinate sequencing and fault management across multiple ADI PSM devices
- Accurate monitoring of output voltage, output current, temperature, and input voltage and current
- Connect directly to regulator IMON pins, 1.8V to 3.3V I²C/SMBus serial interface
- Operating junction temperature is 0°C to 70°C
- Package style is 44-lead plastic QFN
