Energy Monitors

Linear Technology’s energy monitors provide accurate board level energy measurements in addition to other key parameters.  Internal accumulators provide accurate readings of charge, energy and time, with the option of using a convenient internal crystal or a more accurate external crystal as a time base.  The LTC2946 provides current, voltage, power, charge and energy readings for rails up to 100V or beyond using the internal shunt regulator.  The LTC2947 provides the same parametric readings as the LTC2946 and integrates a sense resistor for convenient monitoring of up to +/-30A rails with only 9mA of offset (high dynamic range).
