Multi Cell Synchronous Switch-Mode Charger Reference Design


This reference design: using bq24600: is a highly integrated Li-ion or Li-polymer switch-mode battery charge controller solution. It allows for a highly integrated switch-mode battery charge controller designed specifically to charge Lithium Phosphate battery chemistries. The design contains a highly integrated super capacitor switch-mode charge controller: which offers 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 design 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 design 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.
