Product Summary

The BQ26200PW is a low-cost battery coulomb counter. It works with an intelligent host controller, providing state-of-charge information for rechargeable Li-Ion, Li-Pol, or NiMH batteries. The BQ26200PW 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. The BQ26200PW features 13 bytes of registers, which contain the capacity monitoring and status information.
