## Detailed Description

LTC2946: 12-Bit Wide Range Power, Charge and Energy Monitor.

    The LTC®2946 is a rail-to-rail system monitor that measures
    current, voltage, power, charge and energy. It features an
    operating range of 2.7V to 100V and includes a shunt regulator
    for supplies above 100V. The current measurement common mode
    range of 0V to 100V is independent of the input supply.
    A 12-bit ADC measures load current, input voltage and an
    auxiliary external voltage. Load current and internally
    calculated power are integrated over an external clock or
    crystal or internal oscillator time base for charge and energy.
    An accurate time base allows the LTC2946 to provide measurement
    accuracy of better than ±0.6% for charge and ±1% for power and
    energy. Minimum and maximum values are stored and an overrange
    alert with programmable thresholds minimizes the need for software
    polling. Data is reported via a standard I2C interface.
    Shutdown mode reduces power consumption to 15uA.
