The bq24630 is a highly integrated lithium phosphate switched-mode battery charge controller. The device 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 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.

BQ24630EVM — 用于 BQ24630 多节同步开关模式充电器的评估模块

bq2461x 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。bq2463x 是高度集成的开关模式电池充电控制器，专为磷酸锂电池化学物充电而设计。它们可以为恒频同步 PWM 控制器提供高准确度充电电流和电压调节、适配器电流调节、充电预处理和充电状态监控。bq2461x/bq2463x 在以下三个阶段为电池充电：预处理、恒定电流和恒定电压。当电流达到最低的用户可选级别时，充电将终止。可编程充电定时器可以为充电终止提供安全备份。当电池电压低于内部阈值时，q2461x/bq2463x 会自动重新启动充电周期；当输入电压低于电池电压时，则会进入低静态电流休眠模式。
