Hi Team,

customer feedback that BQ25713 seems cannot meet csutoemr's design.

the system need around 90Watt.

however, BQ25713 datasheet shoed input current limitation is 4A.

Would you please recommend the proper solution for this? is BQ2573X ok for this?

Hi SHH,

TI will release BQ25731 in a month or so, which can handle higher power. Please stay tuned.

Best Regards,

Hi Linhong,

Thanks for feedback.

In BQ25713 EVM, there is mark that VSYS max is 19.36V/8A.

from the Vin to Vsys current, will that limit by BQ25713?

If customer decrease the input sense resistor 10mohm to 0ohm, can that avoid the 4A limitation?

One clarification: the input current register can set to 6.35A based on 10mohm resister, which is above 90W. With a small current sense resister, the input current limit can be even higher.
