数据: bq2431x Overvoltage and Overcurrent Protection IC and Li+ Charger Front-End Protection IC 数据表
bq24314和bq24316器件是高度集成的电路,旨在为锂离子电池提供充电电路故障保护。 IC持续监控输入电压,输入电流和电池电压。在输入过压情况下,IC通过关闭内部开关立即切断充电电路的电源。在过流情况下,它将系统电流限制在阈值,如果过电流持续,则在消隐期后关闭通过元件。此外,IC还监控其自身的芯片温度,如果温度过高则关闭。输入过流阈值是用户可编程的。
IC可以由处理器控制,还可以向主机提供有关故障状态的状态信息。
