BQ24780S

BQ24780S的充电电流,截止电流可以通过SMBUS读取吗?还是通过IDCHG读取的?有没有跟BQ24780S类似功能,但是可以通过I2C读取截止电流的?BQ24780S芯片上有3个管脚(IADP,IDCHG,PMON)是要求接到主控的AD口,但是我的主控没有AD口,想加1个ADC有I2C接口的芯片,请问有没有推荐型号?

Star Xu:

由于IDCHG不是双向拓扑,因此它仅支持放电电流监控器BQ24780s does not have an integrated ADC, so it does not provide a means for directly measuring charging current. The BQ25710 and BQ25713 devices do have an integrated ADC

IADP,IDCHG,PMON这3个管脚不用的话,BQ24780S会缺少哪些功能?不用这3个管脚的话能正常充电吗?截止电流通过哪个寄存器可以设置?

When battery is full or battery is not in good condition to charge, host terminates charge by setting REG0x12[0] to 1, or setting either ChargeVoltage() or ChargeCurrent() to zero.
