    The MAX4172EUA+T is a low-cost, precision, high-side current-sense amplifier designed for a wide range of applications where battery/DC power-line monitoring is critical. It is specifically engineered to provide accurate and reliable current sensing in portable devices such as PCs, telephones, and other battery-powered systems.

    Key Features and Benefits:

    1. High-Side Monitoring Capability:
      • The MAX4172EUA+T excels in high-side power-line monitoring, which is particularly useful in battery-powered systems as it does not interfere with the battery charger’s ground path.
    2. Wide Input Common-Mode Range:
      • The device offers an input common-mode range of 0 to 32V, which is independent of the supply voltage. This ensures that current-sense feedback remains viable, even when connected to a battery in deep discharge.
    3. Precision and Accuracy:
      • The MAX4172EUA+T provides ±0.5% typical full-scale accuracy over temperature, ensuring precise current sensing.
    4. Wide Bandwidth:
      • With a bandwidth of 800kHz (when VSENSE = 100mV), the amplifier is suitable for closed-loop battery-charger and general-purpose current-source applications.
    5. Flexibility and Versatility:
      • The MAX4172EUA+T functions with an external sense resistor to set the range of load current to be monitored, providing a high level of flexibility.
    6. Space-Saving Package:
      • Available in a space-saving 8-pin μMAX or SO package, the MAX4172EUA+T minimizes board space requirements.
    7. Power-Good Output:
      • An open-collector power-good output (PG) indicates when the supply voltage reaches an adequate level to guarantee proper operation of the current-sense amplifier.
    8. Wide Operating Voltage Range:
      • The device operates with a supply voltage range of 3.0V to 32V, making it suitable for various applications with different power requirements.

    Applications:

    The MAX4172EUA+T is ideal for applications such as:

    • Portable PCs (Notebooks, Subnotebooks, Palmtops)
    • Battery-Powered/Portable Equipment
    • Closed-Loop Battery Chargers/Current Sources
    • Smart-Battery Packs
    • Portable/Cellular Phones
    • Portable Test/Measurement Systems
    • Energy Management Systems

    In summary, the MAX4172EUA+T is a low-cost, precision, high-side current-sense amplifier that offers a wide range of features and benefits, making it an ideal choice for various applications requiring accurate and reliable current sensing.
