Part Number: BQ24171 Hi Jeff:
Hello, I have some questions about pre charging that I would like to consult with you
Q1:My battery voltage is 4.4V/2A, and the pre charging voltage set is below 3V to start pre charging. But when my battery voltage just…
Part Number: BQ24171 In bq24171EVM, sense resistor(R2) of value 10 mohm with wattage of 0.5W is used. It was selected based on the input voltage (4.5V - 16V) and load current (5A) right?.
In our design, input voltage will be 12V , load current will be 3A…
Hi Jeff,
I'm going to use 103AT thermistor as it was suggested in bq24171 datasheet. Can you tell me how I can connect 103AT with the battery.
Do, I have to use a use a connector?. Or It has to be connected directly to battery ?
Bcoz in eval board, …

Hi, Ti Power Team
I don't want to charge the battery above 45°C. 1. Do I set it by entering a 45°C resistance value in the R-HOT of the calibration tool? ex) 103AT : 45°C = 4.91K / 60°C = 3.02K 2. If I set the R…
Part Number: BQ24171 Hi,
How do I determine the junction temperature of the TI charging IC (bq24171)? The IC data sheet includes ψ JT: 0.4°C/W. We want to calculate the junction temperature using this coefficient and the measured case temperature…
Part Number: BQ24171 Equation of junction temperatures is Tj = Tc + (ψJT x Power).
Tc = Surface temperature of bq24171' case
ψJT= 0.4 ℃/ W
I have a question about "Power".
The bq24171 is switching, how should I calculate the power …
Part Number: BQ24171 Hi,
We have designed BQ24171 into our PCB. I can share schematic and layout file of the PCB privately if needed.
Alternatively, you can find the files in the TI case: CS1292295
Can you please let us know any feedback for schematic…
Part Number: BQ24171 Hi, TI team
Is there any problem if I change the design as below based on the reference circuit diagram in the datasheet of BQ24171?
