Part Number: BQ25155 With BATT connected, VIN (5V) was turned OFF. ADC_IIN_Current shows approximately 330mA. Why is it flowing even though there is no input from VIN?
When VIN is in the ON state, the current value is approximately normal.
Part Number: BQ25155 Other Parts Discussed in Thread: BQ25150 , Hi,
i would like your feedback about this scenario with BQ25155 or BQ25150.
As reported in the manual:
it seems that we can change the reset behavior.
In our project, the bq25155 is configured…
Part Number: BQ25155 Hello.
I'm able to measure VBat when connected to Vin, but have been unable to get a reading when measuring in active battery mode.
In my current code:
HAL_GPIO_WritePin(GPIOE, GPIO_PIN_2, GPIO_PIN_SET); //Set LP pin on BQ…
Part Number: BQ25155 Hello,
Our customer has a question about minimum headroom voltage from VBUS to BAT.
As I checked in the datasheet and found out it seems to be defined by VDPPM and Ron(PMID to BAT). Since PMID voltage is regulated 4.5V default condition…
Part Number: BQ25155 Hello,
We are currently experiencing an issue in which the BQ25155 does not properly respond to a request for I2C register 0x6F. Normally, the device responds with 0x35. However, when VIN is applied for a brief moment to bring the…
Hi Yuuzi,
I've done some investigating and it looks like the software logic won't execute a write for the register loaded values on the default view, only on the field view. So you will have to open the device with field view
Save registers there…

Operation has been confirmed using BQ25155EVM. The app used is "Battery Management Studio". I would like to perform a charging operation, but the charging current does not flow. The current flowing to VIN5.0V is 10mA or less…
Part Number: BQ25155 According to specifications, the BQ25155 should power up when the MR pin is set low for more than 125 ms (144 ms maximum). However, when tested, we saw only a reliable waking with a pulse duration of 250 ms or more. Measured with…
Hi,
yuuzi kuriiwa said: My question is, does this mean that there is no problem whether the SCL/SCK voltage is high or low regardless of the VIO voltage?
There is no issue if the I2C pull-up voltage is higher than VIO. If it is lower then there may be…
