We have been using BQ2060A circuit but now we would like to replace it by BQ20Z655. When testing BQ20Z655 circuit a failure appeared. After discharging of 4S1P cells it was not possible to start charging again.
Charging and discharging cycle passed correctly 6 times but during 7 cycle it failed.
On the display two segments indicating capacity with outline keep flashing.
Data Flash can´t be rewrite.
For communication with a PC we are using EV2400. I enclose a table with data after a failure.
