Part Number: BQ25723EVM Tool/software: Hi TI e xpert,
When I was testing the EVM, with Vin=14V and Vbat=7V, the system was unloaded, and the switch was operating normally in buck mode. However, when I continued to increase the input voltage to 20V,…
Part Number: BQ25723EVM Where can we find the OrCAD file of the BQ25723EV, it's possible to get it ? Thank you very much for your answer, best regards.
Part Number: BQ25723EVM Other Parts Discussed in Thread: BQ25723 , When testing the BQ25723EVM, the ADC VSYS and VBAT registers of the BQ25723 IC cannot be read after removing the 12V supply voltage.

Part Number: BQ25723EVM Other Parts Discussed in Thread: BQ25723 , EV2400 Hi,
I'm trying to evaluate the BQ25723 by charging two 18650 cells with the Evaluation board (BQ25723EVM). If I understand the datasheet correctly the default charging voltage…
Part Number: BQ25723
Tool/software:
I am a newbie and trying to learn how the chips work so I can eventually move on to designing my own PCB. Since I am a hobbyist, I have opted to try and build this on a breadboard using a QFN to through-hole breakout…
Hi, Duan,
BQ25723 does not support 2mohm current sense. My suggestion is to follow TI BQ25723EVM user guide when starting your battery charger design.

Hi, Liang,
It looks the current sense is to low. The RAC is 2mohm, only 12mV @6A input. You could use at least 5mohm for RAC and RSR.
Let me know if this fixes the issue.
You can also order a BQ25723EVM, thus rule out any layout related noise-issues…
HI MM,
Figure 10-20 shows a FRS transition waveform. It is very quick in transition in the range of tens of microseconds. I would suggest you ordering a BQ25723EVM and try out its FRS function.
