TPS25750: Circuit design with Power Consumer (Sink)

1/2. If you will not be providing VCONN in your system which is permissible in the standard, then you can remove the 4 capacitors in the diagram below and short PP5V to ground. 

3.  The TPS25750 will operate with the two target PDO (Voltage/Current settings) as long as you configure the device to request them as part of the configuration process described within that part datasheet.  www.ti.com/.../tps25750

Please feel free to ask any further questions or click customer things resolved if I have fully answered your questions.

Hi team,

We can not see your attached diagram. Could you attach it again?

Best regards, Yuta Ishii

Dear Branch-san

Thank you for your quick-response.
But my question has not resolved yet.
Please advice about below additional questions.

(1) Although according to your comment,you attached something diagram,I can't view or open it.
(The situation was the same for both IE and chrome.)
Could you attach file directly?

(2) Is there a reference circuit diagram when using TPS25750
under the following two conditions?
・ 5V / 3A (15W) Power Consumer (Sink)
・ 20V / 5A (100W) Power Consumer (Sink)

(3) Is it correct to disconnect (open) "PP5V" terminal
in the case of upper two conditions?

(4) Is it necessary to be controled by I2C in the case of upper two conditions?

(5) How do I set the TPS25750 to operate under the upper two conditions?

Especially I am concerned below case.
・ 5V / 3A (15W) Power Consumer (Sink)
Simply because, if 20V or 15V is outputted by TPS25750,my system corrup due to over rating.

With best regards

Yuti San,

1/2 I am going to attempt to capture a sync only circuit in a more readable format that I should be ready to send Wednesday.

3.  PP5V should be grounded if you do not intend to support a 5V source.

4.  The device does not require I2C control for the stated caes.

5.  The TPS25750 is a fully functional typeC/PD controller.  In the case that you have described, the PD controller will report to the source port that it supports a 5V/3A contract and a 20V/5V contract (requires a signed cable) If the source is able to support 20V/5A and the cable is properly signed, then the sync will request the highest power PDO available.  It is legal for a charger to only support 5V/1.5A according the to type C specification, so it is usually recommended to be able to connect in this case, not necessarily operate.

I will send the Sync schematic out by Wednesday Afternoon.
