Hello ti colleague,
we want to INA2181A4 cooperate with QCC3086 used for earbud charging case product. the QCC3086 ADC reference voltage is 1.8V and have 1023 bits. more details can refer to the picture1.
...
The maximum charging current for single earbud is 180mA.The input was from LDO output 3V. The current resistor value is 40mR.
Please help to check the schmatic of INA2181A4.
