DESCRIPTION
The bq24610/7 is highly integrated Li-ion or Li-polymer switch-mode battery charge controller. It offers a constant-frequency synchronous switching PWM controller with high accuracy charge currentand voltage regulation, charge preconditioning, termination, adapter current regulation and charge status monitoring.
The bq24610/7 charges the battery in three phases:preconditioning, constant currentand constantvoltage. Charge is terminated when the current 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 bq24610/7 automatically restarts the charge cycle if the battery voltage falls below an nternal threshold, and enters a low-quiescent current sleep mode when the input voltage falls below the battery voltage.
