### Problem Description I am experiencing thermal regulation issues on a high-density 10-channel charger board. When charging at 3A per channel, the internal Tdie temperature Target TDIE quickly rises to 120C. At this point, the…
Part Number: BQ25672 I'm design a charger for a device whit a battery pack made up of 4 cells (in series) powered from a solar pannel.
To do that i'm using a BQ25672, i'm wondering if there some critical issue whit the schematic before i send it to…
Part Number: BQ25672 Other Parts Discussed in Thread: BQ25798 the part suppose to be buck charger rather than buck- boost shown in the page 126 of the data sheet
the part is missing in the latest battery management studio
please advise
Thank you…
Part Number: BQ25672 Dear TI Experts,
I am working with a design using the BQ25672 battery charger IC. I am experiencing severe overheating of the BQ25672 IC specifically when a battery is connected and attempting to charge. The IC remains cool when…

Dear TI support, I have a circuit with the BQ25672 and use an Application Note for the auto-restart for a poor source qualification. The configuration of the input circuit…
Part Number: BQ25672 Hi,
We are using the BQ25672 for battery charging and have connected the battery NTC to the TS_ADC pin. In the datasheet, the temperature measurement values are provided in percentage terms.
Could you please provide guidance…
Part Number: BQ25672 Tool/software: Hi jeff, the BQ25672 charger IC, which has overvoltage protection up to 26V. I tested this and when the input voltage exceeds 26V, the IC correctly cuts off the input. However, when the input voltage is reduced back…
Part Number: BQ25672 Tool/software: Hi jeff.
I supplied a voltage ranging from 3.6V to 25V on the VBUS side. When I applied 3.6V to VBUS, the system voltage and battery voltage were both 4.2V. However, when I increased the VBUS voltage beyond 3.6V,…
Part Number: BQ25672 LiFePO4 - S1 Charge current - 3A. Input Voltage 12V
As I understand from the data sheet, this BQ25672 does not support IR compensation of connector and wire resistance to the battery, but it can be done in software.
I made some…
