Tool/software:

Hi team,

What is the internal fucntion connected to C1+/- pins and C2+/- pns? Are these pins connected to internal charge pump?

Also, what is the allowable maximum working voltage of C1, C2, C3 and C4 on the figure 4 on the datasheet?

Best regards,

Shunsuke Yamamoto

    Yamamoto-san,

    The C1+/- and C2+/- pins are indeed used for the internal charge pump. 

    We do not list the maximum working voltage of the capacitors on the datasheet. However, the voltages can reach up to 2xVCC in the worse case scenario. I would recommend capacitors with a voltage rating of at least 10V as a precaution.

    Let me know if that answers your question or if you have any other questions.

    Regards,

    Ethan
