Part Number: BQ76905 Other Parts Discussed in Thread: BQ76907-Q1 Dear,
What are the main differences between the two devices ( BQ76905 vs BQ76907-Q1) , besides the automotive version and the maximum Vbatt value?
Thanks
Part Number: BQ76905 Hi everyone,
I am designing a 5S BMS circuit using the BQ76905 IC. In my design, B+ is connected directly to the load via a cable. The PCB only has B- and P - outputs. Additionally, there is a connector for the cell sense wires…

Hello,
for the design of a mobile device powered by two LiFePO4 cells that can be charged via USB-C, I plan to use the following IC combinations:
- TPS25730…
Part Number: BQ76905 Other Parts Discussed in Thread: UCC27444 Hi Team,
We are using the BQ76905 to control the CHG and DSG pins, which then drive the MOSFETs through the UCC27444 gate-driver IC. Our design includes 14 charge MOSFETs and 14 discharge…
Part Number: BQ76905 Tool/software: Hi TI team,
Currently i am using BQ76905 BMS IC for one of my project with host mcu STM32H523RCT6. I want to use the CRC mode for communication. But it is not working when send the CRC byte then i get NACK. I think…

Hello, I am having a lot of trouble gettting my design to work. Whartever I do, the BQ76905 stays unresponsive to any I2C message I am trying to send to it from the ESP32 microcontroller…
Part Number: BQ76905 Other Parts Discussed in Thread: BQSTUDIO Title: bq76905 — Unable to Charge Unless Both DSG and CHG FETs Are Enabled
Hello,
I am working with the bq76905 to design a BMS for a 2S Li-ion battery (common-port), and I’m facing an…
Part Number: BQ76905 Hello,
I'm working with this BQ76905 device to read the voltage, external temperature, and coulomb counter for a 2-cell lifepo4 battery pack and I've been writing my own driver code to do that. I took a look at the sample driver…
Part Number: BQ76905 In our application, BQ76905 AFE is powered on with 12 V battery.
Internal LDO (REGOUT) is used to power on microelectronics onboard.
During ESD testing we see a dip in the REGOUT voltage resetting the entire system.
ESD pulses…
Part Number: BQ76905 Hi expert,
My customer wants to know why the internal balance MOSFET Rdson range is so large?
The range is mainly caused by temperature or the just the difference among the devices?
If it is caused by temperature, could you…
