BQ25713B: bq25713B

yaacov Abraham

Part Number: BQ25713B

In our system we have the bq25713bB connected similar to the EVB. We connected only a battery to the system. According to the datasheet, by default, the charger is in low power mode (REG0x01[7] = 1) with and The LDO stays off. As in the EVB we connected the VDDA to the REGN via 10 Ohm so VDDA = 0V. In this case the host does not get answer from the bq25713bB on the through the I2C and we can't change the device to moves to performance mode (REG0x01[7] = 0). Does the I2C needs VDDA = 6V ?.

Hey Yaacov,

Do you have a schematic you can of your system?

You also mentioned that you used an EVM before; I assume the BQ25713EVM. Did you change the I2C address on your host to match the I2C address for the BQ25713B? B-version has a different I2C address than the non-B version.

Hi,

My question is does the I2C work when the VDDA = 0V ?

Thanks

Hey yaacov,

How are you powering the EVM? What are your jumper configurations on the EVM? Do you have schematic you can provide?
