BQ26231PW характеристики
BATTERY COULOMB COUNTER, SMD, 26231.
The BQ26231PW is a Charge/Discharge Counter works with an intelligent host controller, providing state-of-charge information for rechargeable Li-ion, Li-polymer, or NiMH batteries. It 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. It features 13 bytes of registers, which contain the capacity monitoring and status information. It is ideal for portable applications with nonremovable rechargeable battery pack.
