Other Parts Discussed in Thread: BQ27500 Hi,
I have one problem with three samples of bq27500, I made two pcb with the datasheet application note and use three bq to solder in this boards but when I connected the system by USB port to the PC, the PC…
Hi,
I am using the latest version of bq Evaluation software from the TI website and can successfully communicate to both our production PCBs and the eval module (HPA291) I have calibrated 30 production boards and have averaged the results - however…
Other Parts Discussed in Thread: BQ27500 , BQ27510-G2 Considering BQ27500/501 for our new board to monitor the battery (Li Ion) that will supply the power to this board. Based on the datasheets, the device will do what I need but I have a question...…
Other Parts Discussed in Thread: BQ27500 Hi,
I'm using BQ27500 v1.30. According to the production flow, after I write the .dfi file to the gauge flash, IT_ENABLE command seems not working. QEN and VOK are still cleared in the CONTROL_STATUS. However…
Other Parts Discussed in Thread: BQ27500-V130 , BQ27500-V100 We have recently upgraded from the bq27500-V100 to the bq27500-V130. It appears in reading the data flash that the offset for the hibernate current is different between the two versions. The…
Hi,
Have a question about the dataflash values
The constant Data Flash->Configuration->Charge Termination->Taper current seems to get the value from bqeasy in step 2B ("what is the maximum taper current of the charger possible considering charger…
Other Parts Discussed in Thread: BQ27500-V130 Hi All,
I'm having some trouble achieving a successful learning cycle on my battery in bqEASY with the bq27500-v130. I've probably run the thing a half a dozen times so far, and every time it fails with…
Other Parts Discussed in Thread: BQ27500 I am trying to connect a production board to the EVSW/EV2300/HPA291 in order to do the calibration step (CC offset, temp and current).
In the slua449e document: "Going to production with the bq275xx" it is written…
Other Parts Discussed in Thread: BQ27500 We have tried to create a golden file for the BQ27500 with the bqEASYtool, but we have encountered a problem::
Setting up the different parameters by the step-by-step method is easy, including changing the OP…
Other Parts Discussed in Thread: BQ27500 Hi
When the system is in standby it draws only 0.5mAh from the battery.
This current is to small for the bq27500 v130 to measure so it has to be calculated by the fuel gauge.
This is not the case…
