Part Number: BQ25170 Hi,
I am using BQ25170DSGR in my design. What will happen if a battery with reverse polarity is connected to this chip out pin? I am not going to use series diode with my battery for reverse polarity protection, because of the voltage…
Part Number: BQ25170 Hello,
We are running worst case analysis on the bq25170 with KSET varying from 270 - 330 we calculate needing approximately a 715 ohm resistor.
The issue is the wide ranging currents. We calculate out with 715 ohms a 374mA_min and…
Part Number: BQ25170 Hello,
I'm trying to use BQ25170 to charge a 3.7 V Li-Ion battery with a maximal charging current of around 450 mA. The circuit is used is mostly based on what is described in the datasheet :
The charging seems to be OK, unfortunately…
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 Hello TI experts,
My customer considers BQ25170 for their new product.
As you know, BQ25170 does not have power path. (VIN directly to the load)
and my customer wants to use 5 LEDs and MCU to indicate charging status. (these leds…

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 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 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…
Part Number: BQ25170 Hi TI Teams,
We have encountered a problem when using BQ25170, that is, when the adapter is always connected, BQ25170 will enter the sleep mode after the battery is full charged, but it will not enter the re-charging states when the…
