LM8850外部的超级电容是必须的吗？

手册中BAL引脚接两个超级电容0.05F到1F，因PCB空间有限放不下这两个大电容。

请问这两个电容是必须的吗？容值是否一定要这么大？

谢谢！

从芯片应用的角度，当然可以不用这两个超级电容！从实际产品对Vout输出电压动态没有特别快速度要求，也可以不用。

若仍有担忧，也可以考虑留上接点，电容放到产品的其它空余空间处，然后通过导线连过来也是个方法。

The LM8850 has an internal balancing circuit that helps maintain voltage balance between the two capacitors
within the super capacitor. The BAL pin regulates a voltage of VOUT/ 2 between the two capacitors. If one
capacitor is overcharged or less charged, the LM8850 will use the balancing circuit to correct this charge
inbalance. The balancing circuit can be turned off/on via the I2C registers (BALMODE – Control Reg01, bit 3).
The balancing circuit also has the ability to stay ON even after the LM8850 is shutting down (BAL – Control
Reg00, bit 4).
