Part Number: BQ27742-G1 Hello, In the datasheet and TRM, there is reference to being able to override the FETs to open them via firmware instructions (See Section 2.2.2.2.1.1 NORMAL Mode in the datasheet):
FET enable override capability is available…
Part Number: BQ27742-G1 Other Parts Discussed in Thread: BQ27542-G1 , BQ27541 Hi Team,
Use BQ27542-G1 to test the lithium battery, the interface is i2c,
is there a sample code in C Programming Language for reference?
Part Number: BQ27742-G1 Other Parts Discussed in Thread: BQSTUDIO Hello there,
We are using many BQ27742-G1 in our products, and we use Battery Management Studio to program the firmware during production time, which doesn't have any problem. However…
Part Number: BQ27742-G1
The I2C syntax is unclear to me in the datasheet: https://www.ti.com/lit/ds/symlink/bq27742-g1.pdf?ts=1611584050250&ref_url=https%253A%252F%252Fwww.google.com%252F There are "Command Codes" (Table 8) which are of the syntax …
Part Number: BQ27742-G1 Other Parts Discussed in Thread: BQSTUDIO Hello, I was testing the fault conditions on the BQ27742-G1, in particular the firmware ones given from calling "SafetyStatus(): 0x1A and 0x1B" (See Section 4.14.1 of the Technical Reference…
Hello Shirish,
Shirish said: Default values are specified in the TRM.
Are they the values I screenshot in my previous reply? Those were the only relevant looking values in the TRM that I could find. The zeros look like they'd be the reset values by…
Part Number: BQ27742-G1 Other Parts Discussed in Thread: CSD87501L , CSD83325L Hi team,
Can you have a look at the following customer issue please? Is there a MOSFET that you recommend to use with BQ27742-G1 instead of uPA2375T1P or CSD87501L?
We…
Part Number: BQ27742-G1 Hi, Team,
Customer want to know Can this chip BQ27742YZFR-G1 work normally at low pressure of 70 kPa and 45℃? And does accuracy matter? I don't see related description about pressure in Datasheet. Could you please kindly give…
Part Number: BQ27742-G1 How are FCC & RM filtered to get smoothened SOC?
FCC and RM get filtered with the same algorithm and frequency?
The SOC jumps mainly come from RM change or FCC change?
As the battery accumulates more cycles, will the filtered…
Hello Sudheer,
Based on the description it looks like the bq27742-G1 is bricked. You will need to replace it.
The screenshot also shows values that are not normal. This is consistent with data corruption.
