BQ24195使用问题求解

Other Parts Discussed in Thread: BQ24195, BQ24195L

TI工程师,您好,我在使用BQ24195时遇到如下问题,请问可能是哪边出了问题!

1、设置REG01寄存器或者拉高CE PIN,Disable Charge,读status寄存器,对应的寄存器显示not charging,但实测还有1A左右的充电电流

2、设置REG07,turn off Q4,但IC仍然给sys供电,读回REG07的状态,确定REG07[5]为1

3、设置ICHG为512mA,但实测充电电流一直在0.9~1A左右

很疑惑是操作寄存器的顺序不对还是硬件设计有问题,急!!!

谢谢。
