More Information

The bq26231 is a low-cost charge/discharge counter peripheral in an 8-pin TSSOP. It works with an intelligent host controller, providing state-of-charge information for rechargeable Li-Ion, Li-Pol, or NiMH batteries. The bq26231 measures the voltage drop across a low-value series sense resistor between the negative terminal of the battery and the battery pack ground contact. By using the accumulated counts in the charge, discharge, and self-discharge registers, an intelligent host controller can determine battery state-of-charge information. To improve accuracy, an offset count register is available. The system host controller is responsible for the register maintenance by resetting the charge in/out and self-discharge registers as needed.
