问题如上,实测的输入使用直流电源进行CV输入,并没有设置MMPT点和采样,发现芯片能够对超级电容进行充电,但是VBAT_OK一直为低电平不会升压,请问这是为什么?具体电路图如下(其中第二幅图没有设置采样点)

您好,请参考下面的内容:
OK_HYST=4.3V from one set of the resistors in the schematic.

The issue could be the parallel, parasitic ~ 1M resistor from solder flux as explained in datasheet section 10. There are 2 ways to test:
1. remove the resistors, clean off the flux and replace there resistors on their edge to minimize surface area for new parasitic resistor
2. replace resistors with 1/3 - 1/10 the value
