数据： bq24600 Stand-Alone Synchronous Switch-Mode Li-Ion or Li-Polymer Battery Charger with Low Iq 数据表
bq24600是一款高度集成的锂离子或锂聚合物开关模式电池充电控制器。它提供恒定频率同步PWM控制器，具有高精度充电电流和电压调节，充电预处理，终止和充电状态监控。
bq24600分三个阶段为电池充电：预处理，恒定电流，和恒定电压。当电流达到最低水平时，充电终止。内部充电定时器提供安全备份。如果电池电压低于内部阈值，bq24600会自动重启充电周期，当输入电压低于电池电压时，bq24600会进入低静态电流睡眠模式。
