Hi,
BQ27421YZFT-G1D fuel gauge chip has the problem of power jump:
1, all the way I2C has a lot of slaves, sporadic I2C lock, can not communicate, can only power off, let the battery protection;
2, the phenomenon is that the data can not be updated, how to charge is 50% power;
3. Pick up the Slaves on I2C one by one, and there are still problems when there is only Gauge left;
4. The direction of the local TI FAE modification plan is to sacrifice power consumption, but the power consumption is very important, and the power consumption cannot be accepted too high;
5, there are currently 3~4 set replaced in the hand, the problem of recurring is more difficult;
Please help support;
It's an urgent case.
Thanks a lot.
BRs
