Hi community,


Our patner have a question about i.MX6DQ VDD_SNVS_IN.

Please see footnote 2 of Table 8 in IMX6DQCEC.

According to this footnote, we understand i.MX6DQ VDD_SNVS_IN consume 1mA only when i.MX6DQ power-up and power supply voltage can supply 1mA.

On the other hand, Table 4-1 in IMX6DQ6SDLHDG Rev.1 says as following.


According to table 13 of the chip data sheet, VDD_SNVS_IN can draw up to 1 mA depending on the application.

For those cases, an external regulator is needed because the PF0100 VSNVS regulator supplies 400 μA.



According to this notes, i.MX6DQ consume 1mA not only when power-up but also when a application is runnning.

So we are confused by these description to understand when i.MX6DQ consume 1mA.


Would you let me know when i.MX6DQ VDD_SNVS_IN consumes 1mA what function in SNVS consume a lot of current to understand it?

This information will help us to judge whether MMPF0100A can be used for supply VDD_SNVS_IN or other LDO is required.
