Part Number: BQ78350-DEVICE-FW Hello,
we are designing an application that retrieve and shows the Life Time data block from a bq78350-R2 gauge.
We found some inconsistency with the Secification of the LifeTime data block returned by the MAC commands 0x0060…

The customer want to know the voltage current temperature precision of this chip.
Does this chip can satisfy the following requirement：
电压检测误差 PCM Voltage Detection Error
Part Number: BQ27Z561-R2 Hi Team，
Suppose Cycle Count Percentage is set to 90%. If the fuel gauge is turned off by pulling down the CE pin after discharging 40% in a new counting cycle, and then pulls up the CE pin, will the accumulated discharge amount…

Dear all, BQ27Z561-R2 datasheet first page schematic presents that sense resistor can be between 1 mOHM to 10 mOHM. However in 9.4.1 Layout Guidelines it is stated that "The device is designed to support a 1-mΩ to 3-mΩ sense resistor…
Part Number: BQ78350-R2-DEVICE-FW Hello Sir:
We have three questions about BQ78350-R2.
1. We want to know that the EC3-EC0 bits of batterystatus display 0x07, UnknownError.
What's the meaning? Why does the device have this message?
2. What conditions…
The REST bit does not indicate the same thing as relax state, REST is when the voltage is stabilized AND in relax state. Relax state is when the current is below the quit current.
Thanks for the document. The drawings there are the exact same as the drawing in the datasheet. Unfortunately, those drawings do NOT show a "TI suggested via in pad" solution. I could no longer wait for a response and have just winged…
Part Number: BQ27Z561-R2-DEVICE-FW Other Parts Discussed in Thread: BQ27Z561-R2 Hi team,
Customer told me, that he could not read right CHEM-ID. So I went to check some samples.
Here my application environment:
- Battery Pack 1S
- NCR18500(1900mAh) CHEM…
