Product Overview
The BQ24172RGYT is a synchronous switch-mode Li-ion and Li-polymer stand-alone 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 bq2417x closely monitors the battery pack temperature to allow charge only in a preset temperature window. It can be adjustable for up to three series Li+ cells. The device charges the battery in three phases: preconditioning, constant current and constant voltage. Charge is terminated when the current reaches 10% of the fast charge rate. A programmable charge timer offers a safety backup. It 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.
- Adjustable charge voltage
