Other Parts Discussed in Thread: BQ25672, BQ25792, USB-PD-CHG-EVM-01, , TPS25750
Hi team,
My customer would like to design a USB-PD system using tps25750d and bq25672 (or bq25792).
The configuration is close to the USB-PD-CHG-EVM-01(www.ti.com.cn/.../USB-PD-CHG-EVM-01).
But in the TIDA-050047,it is said that for a Sink-Only application, 5 V and 3.3V rail can be omitted.(page 7)
In that case, can we floating PP5V and VIN 3V3 pins?
In addition, it is sink-only from USB, if we don't connect USB and use battery to supply, are pp55v and VIN 3v3 need?
Thank you.
