Q: bq24092 High Battery Impedance 

During battery charging, the bq24092, how maximum internal impedance of battery can be accepted?


A: Re: bq24092

Typically the impedance of the cell is around 100mOhms and a few hundred nH of inductance. If the impedance of the cell or connection is too high, it could cause some transients that may cause early termination or unwanted noise.  Reducing the inductance of the connection (shorten or twist wires) or adding output capacitance will help reduce or cancel the inductance.  Try 10uF of ceramic capacitance.
