BQ25672: 工作模式

Part Number: BQ25672

BQ25672,我们需要配置什么寄存器或者功能。使得通过I2C一次配置相关参数就按照I2C配置参数进行充电,而不是现在必须通过I2C反复进行设置才能按照设置参加进行充电否则一会儿就按照默认参数进行充电的。

  • 现在我们出现一个情况,通过I2C设置BQ25672里面一个充电电流限制寄存器,设置值为 1.7A。设置瞬间后是有效果的。不过一两秒中的样子。充电电流由自动变成默认的2A

  • 您好,请参考数据手册24页的内容:

    With the CELL bits stay at 2s battery configuration, when REG_RST bit or watchdog timer expired, the registers are reset to default values with ICHG, VSYSMIN and VREG automatically return to 2A, 7V, 8.4V respectively.
