MP2722 with USBC and without D+/D-

Hi @mayank.gupta,

  1. The D+/D- lines are used for USB type detection. You can use SCL and SDA lines to configure MP2722 via MCU. Kindly refer to this forum post.
  2. Yes, When Vin not present, the Vsys will follow the Vbatt. Yes, a boost will be needed to keep the Vsys at a certain voltage when input is not present. You can boost it up to 3.3V rather than boosting and bucking again, since both of these devices will have their own Iq and will probably drain the battery faster.
  3. You can set the current using Iin_lim, please refer to the Forced Input Current limit on pg 24 of hte DS.
  4. Yes, MP2722 provides Charging and discharging via the BATTFET. Refer to the NVDC section on Pg. 18. MP2722 cannot provide SOC or SOH, however we have fuel gauges which might work for you application.

I hope this helps.
Thank you
Sauarbh
