Cxlb73132a cxlb73132b complete single lithium-ion battery charger with battery positive negative pole reverse connection protection constant current/constant voltage linear control

Cxlb73132a cxlb73132b is a complete single lithium-ion battery charger with battery positive and negative pole reverse connection protection and constant current / constant voltage linear control. Only a small number of external components make cxlb73132a cxlb73132b the ideal choice for portable applications. Cxlb73132a cxlb73132b is suitable for USB power supply and adapter power supply.
Because of the internal PMOSFET architecture and anti reverse charging circuit, no external detection resistor and isolation diode are needed. Thermal feedback can adjust the charging current automatically, so as to limit the chip temperature under high power operation or high ambient temperature conditions. The charging current can be set externally through a resistor. When the battery reaches vfloat (typical value 4.22v), the charging current drops to 1 / 10 of the setting value, and the cxlb73132a cxlb73132b will automatically terminate charging.

       CXLB73132A CXLB73132B 一款完整的单节锂离子电池充电器,带电池正负极反接保护,采用恒定电流/恒定电压线性控制。只需较少的外部元件数目使得CXLB73132A CXLB73132B 便携式应用的理想选择。CXLB73132A CXLB73132B 可以适合USB 电源和适配器电源工作。4i1嘉泰姆

由于采用了内部PMOSFET 架构,加上防倒充电路,所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节,以便在大功率操作或高环境温度条件下对芯片温度加以限制。充电电流可通过一个电阻器进行外部设置。当电池达到Vfloat (典型值4.22V)之后,充电电流降至设定值1/10, CXLB73132A CXLB73132B将自动终止充电。4i1嘉泰姆

当输入电压(交流适配器或USB 电源)被拿掉时, CXLB73132A CXLB73132B自动进入一个低电流状态,电池漏电流在3uA 以下。CXLB73132A CXLB73132B 的其他特点包括充电电流监控器、欠压闭锁、自动再充电和两个用于指示充电结束和输入电压接入的状态引脚。4i1嘉泰姆
