Part Number: BQ25155 Other Parts Discussed in Thread: BQ25150 , Tool/software: Hi BCP team,
My customer is intersted in both BQ25150 and BQ25155.
The differences are highlighted in below e2e thread with the capture from datasheet.

Part Number: BQ25155 Tool/software: Hi team,
Customer used BQ25155's ADC to read battery voltage and the accuracy is bad.
According to customer's description: They charge full battery and voltage is 4.2V but they read ADC and calculate result…
Hi Howard,
As Paul mentions, additional external resistances should be taken into account when calculating R. ITS_BIAS is a fixed typical 80uA bias current so you should expect to use that about that much current.
If there is a 10kOhm resistor in parallel…
Part Number: BQ25155 Tool/software: In the datasheet, VIH on the /CE pin does not have an upper limit value listed, but is there a problem if I control it with a voltage higher than VIO, e.g. 5V when VIO is 3.3V?
Hi Dushyantha,
There is a slight increase in Ibat_active, about 2 uA as compared to /LP being pulled to VDD, but aside from that the device behavior appears to be as expected so this connection should be fine for your solution.
You won't be able to disable…
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…
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…
