Switch from VDD_HIGH_IN to VDD_SNVS_IN of RT family

[fredfu]

Hi,

      In RT1052 RM, there is a bit to control switch from VDD_HIGH_IN to VDD_SNVS_IN, could you help to provide detailed description of the controlling circuit?

   

Best Regards,

there is a internal diode between VDD_HIGH_IN and VDD_SNVS_IN, and this switch has function only in VDD_HIGH_IN and VDD_SNVS_IN powered, otherwise, it will always enable.

Hi  Wayne,

    Thanks. Can the switch be disabled? if customer don't need the channel from VDD_HIGH_IN to VDD_SNVS_IN.

Best Regards,

it can be disabled only when VDD_SNVS_IN and VDD_HIGH_IN both powered.
