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: MSPM0G3518
The AFE BQ76905 we are interfacing with MSPM0G3518 MCU I2C communication. Our HW design is for 4S so we are able to read/write the following parameters from AFE:
Read Individual Cell…
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…
