Part Number: BQ25155 Other Parts Discussed in Thread: BQ25180 , BQ25620 Tool/software: Hi Team TI
My requirement is as listed below
- Charger for 1/2 cell Li-Po Battery (3.7V, 800/1000 mAh) - Buck outputs for: - Bluetooth module (1.7V to 5.5V, 50mA to…
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…
Hi Toshiro,
It looks like I was a bit confused as I was using a BQ25150 for this experiment. The BQ25150 has different startup settings than the BQ25155, particularly VINDPM. VINDPM is disabled by default on the BQ25155, so effectively VIN > VBAT + SLP…
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, I would like to know if the %Icharge value is available and measured when the IN pin is not connected to a supply.
I would like to monitor the board consumption and look like the internal sense resistor is connected to 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…
