Part Number: BQ76952 Other Parts Discussed in Thread: BQ77216
Hi
I have a query need your help.
The CHG output high level of BQ76952 is Vbat+11V, and the low level is Vbat.
After the BQ77216 is triggered, it controls the MOS in the red box and pulls…
Part Number: BQ76952 Hi, We are facing problem in cell measurement in BQ76952 AFE design. First cell drops to 1500mV(approx) randomly when battery is idle. Balancing is also not happening at that time. The nearby cell voltage is also ok. These are the…
Part Number: BQ76952 Hi
The customer design with BQ76952, a fter the load is added, the output voltage of REG2 will drop. Only by disconnecting the current sense line, there is no such problem.
The output of REG2 is 5V, which supplies power to the peripheral…
Part Number: BQ76952 HI, TI team
we are using the BQ76952 for AFE design, as below table show, BQ76962 (no suffix)default is I2C function, and CRC is NOT enable.
And we want to use the CRC function and don't change the chip, so we think is use the…
Part Number: BQ76952 Hi
I have a query need your help.
By configuring the software to open odd or even cell balancing, it has an impact on the sampling error of other sections (see the figure below for detailed data), and not only on cell15. Therefore…
Hello Ramesh, The BQ76952 only supports cell balancing during charging or at rest.
Ramesh Gupta said: After Clear the CB_CHG and CB_RLX and writing into the register using command Subcommands(CB_ACTIVE_CELLS, 0x01, W);
Can you try reading back from CB_ACTIVE_CELLS…
Part Number: BQ76952 Other Parts Discussed in Thread: BQSTUDIO Hi
I have a query need your help.
The test as below:
1. Wake up the MCU to initialize the BQ register data, send a DEEPSLEEP command within 10s and then send it again after a delay of 300ms;…
Part Number: BQ76952 Hi,
I want to use the BQ76952 AFE to automatically control the charging(DCHG) and discharging(DDSG) FETs based on the faults and recovery from the faults. I'm thinking that I can do that by configuring DCHG Pin Config Register &…
Part Number: BQ76952 We use bq76952 manage 16 battery cells , if the cell wire is disconnected with bq76952, how can we read registers of bq76952 to identify the wire is opened.
Thank s
