Greetings,

Is there any way to reduce this device’s power consumption?

I want to increase the connection qty of MCU.

And what I need to note for once the power consumption is too low, will it impact voltage?

Hello,

Looking through the datasheet, I didn't see any intuitive ways to reduce the TSS721A's power consumption. I think reducing communication would help conserve power consumption, but that's probably not possible for your application. However, I did find that you can maximize the output current to the MCU target(s) by reducing RRIDD resistance to 13 kOhms and increasing CSTC up to 470 uF.

Regards,

James
