BQ25713B: PTM MODE

haiqing zou

Part Number: BQ25713B

Hi TI team：

BQ25713B can be set to Direct Through Mode (PTM). What is the maximum output voltage that VSYS can reach in PTM operating mode?

If the output voltage of VSYS remains at 23V, can the chip work normally and will it be damaged? Please help confirm.

Hi, Haiqing,

We have SYSOVP=19.5V. Do not operate VSYS higher than this level.

Regards,

Tiger

Hi Tiger：

Thank you for your reply! Another question is, is there a limit to the maximum current that can be passed through in PTM mode?

Yes, of course, the input current limit is still valid.

Hi Tiger：

What is the maximum input current of the chip in amperes? According to the specifications, IIN: Full range: 12.75 A, LSB: 50 mA.
May I ask if the maximum input current of the chip is 12.75A?

The input current is related to the RAC current sense.

RAC=10mohm, IMAX=6.35A

RAC=5mohm, IMAX=12.7A
