Battery charger IC spec definition - BQ24075

Dear team,

您好，目前新案子使用BQ24075TRGTR charger IC用料，有关电池充电时的应用，请再帮忙确认一下，谢谢

如下是有一些应用上的问题想请教:
VDDPM (output voltage threshold when charging current is reduced)这边的电压定义是指?
VBAT(REG) battery charge voltage 这边是否定义电池最大只能充电到4.24V就不会再往上充电?

Thank you.

Kane

    VDDPM 是进入DPPM mode的阀值, DPPM mode您可以参考数据手册 9.3.4.1.2DPPMMode
    VBAT(REG) battery charge voltage 就是电池的充饱电压,电芯的充饱电压不同,您可以根据数据手册6 DeviceComparisonTable选择合适的芯片
