RST pin on MP2722

Battery Management
1

Hi team,

In the datasheet of MP2722, RST pin is internally pulled up by a 200k resistor. Could you please confirm which power rail is RST pulled up to? Is it pulled up to VCC which is 3.65V?

RST pin will be controlled by a 1.8V IO in my system. I am checking the best solution for level shifter in terms of power consumption.

Thanks a lot.

Hello Peter,
1.8V will be OK as the logic high is 1.3V and logic low is 0.2V. See below.

I will check internally for confirmation on the pull up voltage value and get back to you.

Hi Peter, wanted to follow up on this post. RST is pulled up to VCC.
