BQ24616 描述
The bq24616 is highly integrated, JEITA (Japan Electronic Information Technology Association) guideline compatible, Li-ion or Li-polymer switch-mode battery charge controller. It offers a constant-frequency synchronous switching PWM controller with high accuracy charge current and voltage regulation, charge preconditioning, termination, adapter current regulation, and charge status monitoring.
The bq24616 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. The bq24616 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
