Hi,
My gauge responded properly before. I checked the voltage reading also. Now I was trying shutdown mode, but I couldn't. Now my gauge is not giving voltage readings also. How to cross verify whether the ic on bq27742 evm is working fine. I checked current, it is giving 400uA current, not entering into shutdown mode.
Thank you,
Kavya.
Hi Shirish,
I tried with connecting battery to pack+ and pack-. and removed after sometime so that gauge might be wake. I think gauge is not in shutdown mode. Because, I'm getting 400uA, which is not range of shutdown current. Correct me if I'm wrong. I checked VREG25 pin by connecting CELL+ and CELL-. I'm getting 0.4V on it. Is it ok. Or should it be 2.5v on power ON.
Thanks in advance,
Kavya.
Hello Kavya,
VREG25 will be at 2.5V when not in shutdown. Note that cell should be connected between CELL+ and CELL- and charger should be connected to PACK+ and PACK-. The cell connection is never typically removed.
