评估模块bq24600/bq24620/bq24640 。该bq24600是高度集成的锂离子或锂聚合物开关模式电池充电控制器。Evaluation Module for bq24600/bq24620/bq24640. the bq24600 is a highly integrated Li-ion or Li-polymer switch-mode battery charge controller. The bq24620 is highly integrated switch-mode battery charge controller designed specifically to charge Lithium Phosphate battery chemistries. The bq24640 is highly integrated super capacitor switch-mode charge controller. The devices offer a constant-frequency synchronous PWM controller with high accuracy charge current and voltage regulation, adapter current regulation, termination, charge preconditioning, and charge status monitoring, The bq24600/bq24620 charges the battery in three phases: preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches a minimum user-selectable level. A programmable charge timer provides a safety backup for charge termination. The bq24600/bq24620 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.
