Battery Management

Hi, I want to make sure that NTC1 and NTC2 pin can be left unconnected when disable them through I2C.
Is this right?
Kind regards, Robert

Hello Robert,

Can you please share which IC you are working with?

Thanks!

I am planning to use the MP2722GRH-0000-P charger IC with unconnected NTC1 and NTC2 pin. The MP2722 will be controlled via I2C by a µC in the application. From my experience, many charger ICs do not support open NTC pin, therefore my question.

I have not worked with this device yet. However, from the DS page 20 “Jeita Thermister Qualification” , I would agree with your viewpoint:
