Hi,
I have some problems to communicate with bq24250RGE. The device never send ACK when the MCU sends the address. (I'm using 0x6A).
I checked all the connections. Also I used a logic analyzer to verify the i2c data, but it is fine.
The SCL line is running at 10Khz and the signal wave has a very good shape.
Other tests I have done:
> I connected VIN and I could verify that I get a good VSYS output (The switching is working ok). In this condition the i2c still not working.
> When put CE to ground, I don´t see any response on STAT pin or INT pin, but I still have a good output on VSYS. The battery current on this situation is zero.
> When I connect and disconnect VIN, I have a pulse on INT pin. This pulse has 250us width.
What other test do you recommend to verify the proper device functioning?.
See attached the schematic I'm using.
Thank you in advance.
Best Regards.
Lucas
