Dear. I need help in the following question
I work in the development of a wearable device and its main use is to record ECG signals. This is powered by a 3.7V Li-ion battery. This battery is not accessible to the user, but to charge it through a USB port that must be connected to a PC.
The user should not use the device while it is charging the battery. In order to comply with the IEC 60601 standard, I need to clarify if it is necessary to make an isolating barrier in the device. I have read a lot on the subject, but there is no clear answer to answer my question.
Some indicate that it is not necessary to isolate the circuit, but others indicate that yes.
The device is planned to be commercialized in the US market. Based on this data, should I add some isolator to the USB stage?
I appreciate your help on the subject.
