We uesd PF3001 in our i.MX6UL board, the "LICELL" pin of PF3001 is connected to the external Coil cell(65mAh), and the "VDD_SNVS_IN" of i.MX6UL is connected to the "VSNVS" of PF3001.(The "VSNVS" is sourced from the external coil cell when power off). But the voltage of coil cell is dropped fast while the board is power off, it will be dropped nearly 100mV every day. What caused the consumption? Is it the CPU? Thank you.
