    High Voltage I2C Current
    and Voltage Monitor
    Features Description Wide Operating Voltage Range: 7V to 80V
    12-Bit Resolution for Both Current and Voltages
    I2C Interface
    Additional ADC Input Monitors an External Voltage
    Continuous Scan and Snapshot Modes
    Shutdown Mode (LTC4151) Reduces Quiescent
    Current to 120µA
    n Split SDA for Opto-Isolation (LTC4151-1/LTC4151-2)
    n Available in 10-Lead MSOP, 10-Lead 3mm × 3mm
    DFN and 16-Lead SO Packages The LTC®4151 is a high side power monitor that operates
    over a wide voltage range of 7V to 80V. In default operation
    mode, the onboard 12-bit ADC continuously measures
    high side current, input voltage and an external voltage.
    Data is reported through the I2C interface when polled
    by a host. The LTC4151 can also perform on-demand
    measurement in a snapshot mode. The LTC4151 features
    a dedicated shutdown pin to reduce power consumption.
    The LTC4151‑1/LTC4151-2 feature split I2C data pins to
    drive opto-isolators. The data out on the LTC4151-1 is
    inverted while that on the LTC4151-2 is not. n n n n n n Applications –48V Telecom Infrastructure ...
