The over-discharge protection value is set to 5V. After the discharge protection, the voltage returns to more than 6V without load, resulting in the battery actually only being able to be discharged t...
The next few years will see a dramatic change in the way people view the high-tech world. We are just beginning to realize that the electronics industry will play a major role in solving the problem o...
[size=10.5pt][/size] [size=10.5pt]The picture shows the location of the five pins. It is a SMD package, and the size is about the same as SOT23. Supplement: I just checked and found that the package i...
The voltage can only be stabilized to about 2.5V each time, resulting in the inability to detect the current value above 2.5V (below 3A), so it cannot work when entering the DSP chopping process. Is t...
