Abstract
A power management integrated circuit for monitoring a parameter of a power system includes sensor interface circuitry, first logic, at least one random access memory, second logic, and a communication interface. The sensor interface circuitry is operative to receive and process signals representative of voltage and current in a power system. The first logic is operative to receive the signals and produce at least one power parameter. The random access memory is operative to store the at least one power parameter. The second logic is operative to process at least one incoming communication packet and generate at least one outgoing communication packet encapsulating the power parameter. The communication interface is operative to process the at least one incoming communication packet and transmit the at least one outgoing communication packet. The power management integrated circuit may also include a geographic positioning system receiver and a real time clock.
