Part Number: TPS25750
Could you please review my schematic with the BQ25713 charger?
I'm using them in this mode:
The BQ25713 is connected to an 1S2P battery.
I see two issues with the TPS25750 configuration.
pin10 \i2cs_irq and pin 18 \i2cm_irq should be pulled up to LDO_3V3. This will prevent any IRQ from being triggered before the part has booted.
I do not see any issue with BQ25713, but I do not directly support that part. I suggest that you submit the same schematic to the BQ25713 team for further review by them
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Chuck Branch:
Please update the TPS25750 datasheet that currently states "Tie to ground if unused" for the I2C IRQ pins.
In reply to 6145095:
I have that in process now.
Since the BQ25792 is available now, would you suggest to use that instead of the BQ25713?
I also have a question regarding the Integrated USB Type-C® power delivery (PD) and charging reference design for 2-4 cell batteries" ref design.
Why are these regulators on the schematic when the VIN_3V3 net can be tied directly to LDO_3V3?
Another thing I noticed was the ref design grounded pin 10 and 18 on the TPS25750. Is that incorrect?
