    EVL9988

    EVL9988 promotional board based on L9988 device for battery managements system

    Parameters
    Target ApplicationAutomotive Battery Management System (BMS)
    Core ProductL9965T
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeNot Applicable
    RoHs compliantNot compliant
    GradeIndustrial
    Package NameCARD
    Description

    The IC board integrates the L9988 BMS device, a complete solution for monitoring, balancing, and protecting battery packs composed of up to 4 series-connected Li-ion or Li-polymer cells, together with an SPC582B50E1 microcontroller, to provide a full system platform.The L9988 continuously measures...

    Key features
    Key features
    • Measurement of 4 single-cell voltages, withover/undervoltage detection
    • Measurement of stack voltage, with over/undervoltage detection and plausibility check vs. sum of cells
    • Measurement of battery current (range ± 1500 A), with overcurrent protection
    • Measurement of Coulomb counting for SoC estimation
    • Continuous short-circuit detection
    • Passive cell balancing (max 200 mA) supporting time-continuous and PWM modes, with synchronized odd-even channels balance
    • Measurement of battery pack temperature through an externalNTC, with OT/UT detection
    • Configurable double watchdog (Q&A WD and time-windowedWD)
    • Separate the charge (CHG) and discharge (DCHG) controlpaths by integrating a dual high-side VGS pre-driver: one channel drives the discharge high-sidedriver, while an external pre-driver independently controls the charge high-side driver
    • Integrated PMIC with configurable regulators (BOOST, VCORE, VCC, CAN, VSTBY, VTREF regulators)
    • The possibility to interface the device via SPI from theMCU located on the EVL998 board
