Part Number: BQ76930

Hi,

I work on BMS using BQ7693003 and STM8L . I have faced a problem.

STM8L sent Start Bit and Slave Address(0x08) but BQ76930 doesn't response ACK to STM8L.

Best regards

Hi,
We are currently out of the office but one of our engineers will come back to you when we return.

Thank you for your understanding.

Hi User,

The BQ76930 addresses (0x08) is a 7 bit address. The read/write bit is concatenated as the LSB for an 8 bit address byte on the bus. So you should see 0x10 on the bus for a write and 0x11 for a read. Check the documentation on the tool for how to enter the address for your programming environment.
