The TI E2E™ design support forums will undergo maintenance from July 11 to July 13. If you need design support during this time, open a new support request with our customer support center.
Hi Aditya,
Aditya Patil said: You were also right—we realized the current EVM we have is populated with the TPS25750 instead of the TPS25751. We've placed an order for the correct EVM, but in the meantime, is it possible to replace the TPS25750 with a…
Part Number: BQ25798 Tool/software: HI TI
I want to use the BQ25798 to charge a 4S lithium battery. My circuit configuration is as follows: PROG is set to 17.4K, power input is VBUS 2 12V 1A, SYS output reaches VSYSMIN 12V, but when I connect the battery…
Part Number: BQ25798 Tool/software: Hello,
i'm using the BQ25798 battery charger to charge a 3S battery pack. We are powering the VBUS with a laboratory power source set to 12V, not USB connected, no MPPT. The problem is similar to this:

Hello Sai,
sai bandaru said: The session begins with the battery charging normally via the VAC2 input. When the USB port connected to VAC1 is compromised, the Dynamo charging stops and the IBAT ADC reports 0 mA. Once the USB port is either removed or…
Part Number: BQ25798 Tool/software: Hello Ti, I am using Bq25798, I would like to check if excess temperature rise is effecting the power down of system or not, I am unable to find the hex value through which I can get it. and also how can I avoid this thermal…
Part Number: BQ25798 Tool/software: Hello TI Support Team,
I'm using the MAX17261 fuel gauge to estimate the State of Charge (SoC) for a battery pack made from 2x LG 18650 MJ1 3500mAh (Green) cells. The nominal battery pack specifications are:

Part Number: BQ25798 Tool/software: Hi Ti team,
The BQ25798 is currently used to charge a 1P3S lithium battery from a 12V adapter and supply power to the system. We are evaluating whether we can remove the battery and use only the 12V adapter to power…
Part Number: BQ25798 Tool/software: Following the previous post, I just had another IC on fire today even though all the transient protections were there, so the problem is probably not from the transients of the MOSFET turning the system on and off…
Part Number: BQ25798 Tool/software: Hello, Please review the schematic and share your feedback. I have a question regarding the system voltage, When VBUS is present at the input, is the system voltage (VSYS) directly equal to VBUS, or does it depend on…
