More Information

The bq24171 device is highly integrated stand-alone Li-ion and Li-polymer switched-mode battery charger with two integrated N-channel power MOSFETs. The device offers a constant-frequency synchronous PWM controller with high-accuracy regulation of input current, charge current, and voltage. The bq24171 closely monitors the battery pack temperature and allows charge only in a JEITA profile-compatible window with a lower charge rate at a low temperature and a lower charge voltage at a high temperature. The bq24171 device charges the battery in three phases: preconditioning, constant current, and constant voltage. The bq24171 charges up to 3-series cells with an adjustable cell voltage.
