voltage control

[YuCh_3947976]

Can I use the button of the  to control a external voltage that it's like a voltage switch?

or have any method to realize it?

my input voltage is 12V.

Thanks!

Hello Yu Ming,

I am not exactly sure about your requirement from the description given. I will try to answer from my understanding of your question. First of all, the absolute maximum voltage PSoC 4 can deal with is 5.5V(when VDD is 5V). So you will not be able to use it alone for 12 V switching. You have to add additional circuitry for the switching. Could you please let us know your exact application?

Best Regards,

I just want to let PSoC 4 EVB be like a voltage switch.

But it's the same as I think,the maximum of the input voltage is around 5V.

it seems to need a additional circuit to realize it.

Hello Yu

In that case you need additional circuitry as specified in the 1st response.
