I'm currently building a Li-Ion battery charging circuit which has a 5V/2A input. It should implement load-sharing in order to keep the output alive during charging.
For charging, I found the BQ25606 IC from Texas Instruments and it seems to fulfill all of my requirements. However, one aspect confuses me when looking at the datasheet. It states "58-μA Low Battery Leakage Current with System Voltage Standby". The leakage current is only mentioned at the front page and I've had a hard time thinking of what it might refer to.
Does that mean that when the charging cycle is terminated a continuous current flow of 58μA slowly discharges the battery? The Li-Ion battery I want to use discharges less than 5% per month. Do these two discharging processes add up? Or am I totally mistaken and the 58μA refer to something completely different?
