Linear Technology Corp. introduces the LTC2945, a wide range I²C system monitor that monitors the current, voltage and power of any 0 to 80 V rail. In many cases, prior power monitoring solutions are limited to 3 to 5 V supplies and monitor voltages less than 36 V, requiring additional circuitry to monitor higher voltages. The LTC2945 has flexible power supply options, deriving power from a 4 to 80 V monitored supply, a 2.7 to 80 V secondary supply, or from the onboard shunt regulator.
