UCC3911DP-1概述

    Product Introduction
    The UCC3911 is a highly efficient and reliable integrated circuit designed specifically for protecting sensitive lithium-ion (Li-Ion) and lithium-polymer (Li-Pol) battery packs. This device serves as a two-cell battery protector that integrates an on-chip series FET switch, making it cost-effective and reliable for use in consumer electronics. Its primary function is to safeguard against overcharging and overdischarging of battery cells within a two-cell pack, ensuring longevity and safety.
    The UCC3911 finds its applications in portable electronics such as PDAs, camcorders, digital cameras, and private mobile radios. By effectively managing battery charge and discharge cycles, this IC ensures optimal performance in demanding environments.
    Technical Parameters
    Here are the key technical specifications and performance parameters of the UCC3911:
    | Parameter | Minimum | Typical | Maximum | Unit |

    | Overvoltage Threshold (VOV) | 4.15 | 4.20 | 4.25 | V |
    | Undervoltage Threshold (VUV) | 2.42 | 2.50 | 2.58 | V |
    | Undervoltage Recovery Threshold | 2.90 | 3.00 | 3.10 | V |
    | Short Circuit Current Threshold | 3.5 | 5.25 | 7 | A |
    | Power Drain in Sleep Mode 3 µA µA |
    | Short Circuit Delay Time (tDLY) 100 µs µs |
    | Maximum Operating Temperature 70 | 150 | °C |
    | Minimum Operating Temperature | -20 °C |
    This IC supports a wide range of operating conditions, from -20°C to 70°C, and offers precise voltage regulation to ensure safe operation.
    Product Features and Advantages
    The UCC3911 stands out with its innovative features and advantages:
    1. Dual-Protection Mechanism: It safeguards against both overcharging and overdischarging, preventing catastrophic failures in Li-Ion and Li-Pol batteries.
    2. Low Power Consumption: With a power drain of approximately 20 µA, it minimizes battery energy loss during standby.
    3. On-Chip Series FET: Eliminates the need for external FETs, simplifying design and reducing costs.
    4. Short Circuit Protection: Delivers robust protection with a nominal delay of 100 µs before activating, adjustable via an external capacitor.
    5. Compatibility: Designed to work seamlessly with a variety of portable electronic devices, enhancing reliability and efficiency.
    These features make the UCC3911 a market leader in battery management solutions, providing superior performance and competitive edge in consumer electronics.
    Application Case Studies and Usage Suggestions
    Application Example:
    The UCC3911 is ideal for battery-powered handheld devices like PDAs and digital cameras. Its integration with external components ensures effective protection against high peak load currents and sudden short circuits.
    Usage Suggestions:
    - Temperature Management: Ensure proper thermal management of the IC, especially in high-current applications. Use isolated copper pads for heat sinking.
    - RC Filtering: Add RC filters on the battery sense lines to mitigate false undervoltage triggers caused by capacitive loads.
    - Initialization: Use the CE pin to initialize the device during assembly, ensuring smooth operation and minimizing power consumption during storage.
    By following these recommendations, users can maximize the lifespan and reliability of their battery systems.
    Compatibility and Support
    The UCC3911 works harmoniously with a wide range of compatible devices, including chargers and load systems. Texas Instruments provides comprehensive support, including detailed datasheets, application notes, and customer service to address any issues promptly.
