The 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. An internal 16-bit ADC monitors sixteen output voltages, two input voltages, and die temperature. In addition, odd numbered channels can be configured to measure the voltage across a current sense resistor. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple LTC Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.

Product Detail

The DC2198A is a demonstration system for the LTC2980 16-channel I2C/SMBus/PMBus power system manager with EEPROM. The LTC2980 monitors and controls 16 power supply rails. The DC2198A demonstrates the ability of the LTC2980 to sequence, trim, margin, supervise, monitor, and log faults for sixteen power supply rails. Each power supply channel’s output voltage is monitored and the LTC2980 monitors its own internal die temperature.
