LTC4151IS-2#TRPBF概述

    Product Introduction: LTC4151 High Side Power Monitor
    The LTC4151 is a high-side power monitoring IC developed by Linear Technology. It provides precise current and voltage monitoring over a wide operating voltage range of 7V to 80V. Key functionalities include:
    - High side current sensing.
    - Input voltage measurement (with up to 102.4V full-scale).
    - Measurement of an additional external voltage (up to 2.048V full-scale).
    - A dedicated I²C interface for data reporting and control.
    This versatile product is used in a broad spectrum of applications such as consumer electronics, telecommunications infrastructure, automotive systems, and industrial equipment. Its 12-bit ADC ensures high-resolution monitoring, making it suitable for demanding applications where accuracy is critical.
    Technical Specifications
    Below are the key technical parameters of the LTC4151:
    | Parameter | Typical Value | Unit |
    |
    | Operating Voltage | 7V to 80V | V |
    | Supply Current (Normal Mode) | 1.2 to 1.7 mA | mA |
    | Supply Current (Shutdown Mode) | 120 µA | µA |
    | Input Voltage Reference | 2.048V | V |
    | Accuracy | ±1.25% (C-grade) | % |
    | Resolution | 12 bits | Bits |
    | Input Current (SENSE+) | 5 to 9 µA | µA |
    | Input Current (SENSE-) | 0.1 to 1 µA | µA |
    | Shutdown Input Threshold| 1 to 2V | V |
    Additionally, the LTC4151 supports continuous and snapshot modes, and the split I²C data pins (LTC4151-1/LTC4151-2) allow for opto-isolation. Packaging options include 10-pin MSOP, 10-pin DFN, and 16-pin SO packages.
    Product Features and Advantages
    Unique Features:
    1. High Precision: The LTC4151 employs a 12-bit ADC with excellent accuracy and low integral nonlinearity.
    2. Low Quiescent Current: Its shutdown mode reduces current consumption to 120µA, making it energy-efficient.
    3. Wide Operating Range: Supporting voltages from 7V to 80V, it adapts to diverse power supply environments.
    4. Split I²C Pins: The LTC4151-1/-2 variant allows for opto-isolated communication.
    Market Competitiveness:
    The LTC4151 excels in its ability to monitor high-side current and voltages simultaneously with minimal intervention from the host processor. Its advanced snapshot mode and compatibility with standard I²C protocols make it an ideal choice for modern IoT, automotive, and industrial applications requiring real-time monitoring and control.
    Application Cases and Usage Suggestions
    Applications:
    - Telecommunications Infrastructure: Monitoring power distribution across high-voltage systems.
    - Automotive Electronics: Battery management systems and DC-DC converters.
    - Industrial Systems: Motor controllers and process automation devices.
    - Consumer Electronics: Smart home appliances and portable devices.
    Use Case Example:
    An application circuit might involve monitoring a high-side power rail feeding a motor driver. By connecting an external sense resistor between the SENSE+ and SENSE– pins, users can measure the high-side current with an 81.92mV full-scale differential voltage. Additionally, the ADC can concurrently measure the input voltage and an external voltage.
    Usage Tips:
    - Ensure the sense resistor's value aligns with the expected current range for accurate monitoring.
    - Utilize the snapshot mode when one-time measurements are sufficient to conserve processing resources.
    Compatibility and Support
    The LTC4151 is compatible with most standard I²C buses, ensuring seamless integration with existing electronic systems. Linear Technology offers robust support, including comprehensive documentation, sample kits, and technical assistance to help engi
