    LTC4151
    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 120ВµA
    n Split SDA for Opto-Isolation (LTC4151-1/LTC4151-2)
    n Available in 10-Lead MSOP, 10-Lead 3mm Г— 3mm
    DFN and 16-Lead SO Packages The LTCВ®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 ...

    Power Monitor for Automotive and Telecom Applications
    Includes ADC and I2C Interface – Design Note 452
    Dilian Reyes
    Introduction
    The LTC В®4151 is a high side power monitor that includes
    a 12-bit ADC for measuring current and voltage, as well
    as the voltage on an auxiliary input. Data is read through
    the widely used I2C interface. An unusual feature in this
    device is its 7V to 80V operating range, allowing it to cover
    applications from 12V automotive to 48V telecom. socket would drain the battery considerably faster than
    the GPS. The digital information from the LTC4151 high
    resolution and accurate 12-bit ADC can be interpreted
    and displayed on an in-dash screen, or used by the host
    system to shut down the channel to avoid fully draining
    the battery.
    Telecom Power Monitoring with PoE
    One major advantage of the wide range input voltage
    of the LTC4151 is the ability to monitor higher voltage
    applications such as those used in telecommunications. The emerging IEEE802.3af Power over Ethernet
    (PoE) standard has gained much interest in the past
    few years. Automotive Power Monitoring
    Automobile batteries serve more systems than ever
    before, many of which operate when the battery is not ...

    DESIGN FEATURES L Voltage and Current Monitoring from
    7V to 80V in 3mm Г— 3mm DFN-10
    by Zhizhong Hou
    Introduction
    Accurate power supply voltage and
    current monitoring is increasingly
    important in everything from industrial and telecom applications to
    automotive and consumer electronics.
    A complete power monitoring system
    typically includes a sense resistor, a
    precision amplifier, an analog to digital
    converter (ADC) and a proper interface
    to report data to a host controller. The
    LTC4151 and LTC4151-1 combine all
    of these components (except the sense
    resistor) into one IC, resulting in a full
    featured, rugged and simple-to-use
    solution for accurate high side current sensing and voltage monitoring
    (see Figure 1). The LTC4151 and
    LTC4151-1 offer the benefits
    of high side current sensing
    without any of the usual
    complexity. Each integrates ...
