BQ24171 Description
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-patible window with a lower...
