Hi,
在MSP430F6721, 我把2.7v电池连到DVCC管脚，把另外一个3V电池连到AUXVCC1，电源切换后，工作爱AUXVCC1，我发现在DVCC会有反向电流输出，这样的话会给这个管脚接的电池充电，会损害电池，请教这是怎么回事?
I connect DVCC to one battery (2.7v), and connect AUXVCC1 to another battery(3v), I found after switchover, AUXVCC1 is working power supply, it still ouput current from DVCC pin, which will recharge the battery connected to DVCC. This is not what I want, this battery is not re-changable battery, this behaviour will harm the battery. I do not want to one diode between DVCC and battery, which will waste 0.1v's power, how should I do?
Appreciate in advance,
Asky
