Description
General part information
BQ24171 Series
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.
The bq24171 charges the battery in three phases: preconditioning, constant current, and constant voltage. The device is adjustable for up to three series Li+ cells.
Charge is terminated when the current reaches 10% of the fast charge rate. A programmable charge timer offers a safety backup. The bq24171 automatically restarts the charge cycle if the battery voltage falls below an internal threshold, and enters a low-quiescent current sleep mode when the input voltage falls below the battery voltage.
