Full featured power system manager with accurate input current and energy metering

February 25, 2016 // By Luc Desimpel

Systems with multiple power rails are becoming more efficient, but increasingly complex and difficult to design. In such systems, operating costs and complexity have shifted the power system design paradigm. To adapt, groups of power supplies need to be controlled and monitored to manage efficiency, to coordinate sequencing, and to measure power and energy consumption. Linear Technology’s Power System Managers trim supplies to improve efficiency, monitor supply rails to help identify inefficiencies, and supervise voltages, currents and temperatures. For abnormal events, faults are generated and relevant system information is stored to an EEPROM fault log to help with system debug.
