BQ24630EVM

评估板, BQ24630多单元同步开关模式电池充电器

The is an evaluation module for bq24630, a highly integrated switch mode battery charge controller designed specifically for lithium phosphate batteries. It offers a constant frequency synchronous PWM controller with high accuracy current and voltage regulation, charge preconditioning, termination, adapter current regulation, and charge status monitoring. The bq24630 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 bq24630 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.
