Features

  • Ultra-low current consumption:

    • Typical 100-μA when in standby mode

    • Typical 10-μA when in shipping mode

  • High cell voltage accuracy without calibrations:

    • ±5 mV at 25°C; ±10 mV at 0°C–60°C; ±15 mV at –40°C to 85°C

  • Robust battery cell protection, including:

    • Primary: cell overvoltage, cell undervoltage, two levels overcurrent discharge, overcurrent charge, discharge short circuit and overtemperature

    • Secondary: cell over voltage, cell undervoltage and overtemperature

  • Other system protections, including: cell open wire and host watchdog

  • Support random cell connections

  • Reverse charger and high voltage on PACK side

  • High-side N-channel MOSFETs and strong driving capability
