my customer is using INA220 in power monitor module, but we meet an issue, could you help to give some advice? thanks.
here is the schematic, VCC5V is 5V. but sometimes when poweroff the board, VCC5V will drop to 2.2V.
if the power input recovery to 48V, VCC5V recovery to 5V, but the voltage detector won't have 48V warning, still low voltage. when make VS pin drop to 1.5V and recovery to normal mode, it will work. could you give some advice?
