Part Number: BQ25170 Hi,
I found BQ25170 VSET table as below. If I need 4.28V charge, does it possible to adjust VSET resistor to maybe 25k?
or it fixed 4.2 or 4.35?
Or any similar charger can support 4.28V charge for LiFePO4?
Thanks!
Jeff

Part Number: BQ25170 Hi Team,
Hope you are doing well!
I have a question regarding BQ25170J. From BQ25170J datasheet there are 2 different connections for STAT/PG pins: connect to Vref & Output:
Can you advise which connection you should use? What…
Part Number: BQ25170 I am using a BQ25170 to charge a LiFePO4 battery. The product can run from external 12V power or from the internal battery. There are times that the 12V power is removed for a long time and the battery can fully discharge to the point…
Part Number: BQ25170 In our application, the charge current has to be 10mA.
datasheet bq25170: For charge currents below 50 mA, an extra RC circuit is recommended on ISET to achieve more stable current signal.
I didn't find a schematic and calculations…
Lumina Gui said: That is, w hen the battery is fully charged, remove the adapter and re-plug it in. There will be a charging current of about 54mA, which will last for one night.
54mA is pre-charge current, 20% of Fast Charge. R-ISET = 1100 ohms will set…

Hi TI!
I'm developing a board that will have 10 x BQ25170's on it. To reduce the BOM, I'm wondering if I can share the resistor-networks for ISET and VSET between these 10 IC's or do I have to supply each BQ25170 with…
Part Number: BQ25170 Other Parts Discussed in Thread: BQ25180 Hello. What is the relationship between VIN and VDO? On the datasheet, for example, it is stated that when IOUT is 500mA, the dropout will be about 425mV. For example, if the input voltage is 4…

My customer has a problem when use BQ25170 STAT pin to show charging status.
The STAT pin will blink under fault condition, which means MCU can't just trigger a high level voltage…
