TCA5405RUGR

The LTC®2978 is an octal, digital power-supply monitor, supervisor, sequencer, and margin controller. Eight output channels can be managed per user defined configuration settings. Supervisory functions include fault OV/UV threshold limits for eight output channels and one input channel. Programmable fault dependencies and responses allow the power supplies to be disabled with optional retry after a fault has been detected. Serial bus telemetry allows eight output voltages, one input voltage, die temperature and fault status to be monitored..
