Problem in I2c communication with the bq28z610 IC

Other Parts Discussed in Thread: BQ28Z610

Hello,

I am evaluating the bq28Z610 battery fuel gauge with our custom board.I want to flash the data into this IC using the freescale's controller.

I connected the SDA and SCL line of this fuel gauge with MCU's SDA and SCL line.I also place the external pull up in this line.I took the MCU as the master.

But, I can not able to communicate with this chip.I have also seen the I2c SDA and SCL line wave form on the CRO. From the debugging with CRO, i founded that i am get  NAK pulse on the SDA line.

I followed the below approaches for the debugging.

1) I checked with the 100khz, 400kHz clock speed.

2) I also check with and without the pull up register.

3) I also checked with 10 k pull up register.

I attached below schematic diagram and I2c wave form 's screen shot for your reference.

 

Please help us to resolve this issues.

Please let me know if you need the more infromation from the our side.

Thanks,

Parth
