USB EZ-PD™ Type-C Forum Discussions

For the CYPD4155-96BZXI, what are the VOL and VOH specifications on the VBUS FET control output pins (VBUS_P_CTRL_P1 and VBUS_C_CTRL_P1) ?  Similarly, what are the VOL and VOH specifications on VBUS_DISCHARGE_P1 and OVP_TRIP_P1? Do the specifications SID.GIO#33-#36 in the EZ-PD™ CCG4M manual (Document Number 002-11084 Rev. *C) apply to these pins in this mode (see attached)?

What is the UVP threshold on VCONN_MON_P1?

Finally, regarding VBUS_P_CTRL_P1 and VBUS_C_CTRL_P1 with the firmware that is shipped from the factory in the IC, are these signals active-low or active-high?

Thanks, Hal

I installed EZ-PD Config Utility on Windows 10 (64bit).
When I double-click the desktop icon or use the App menu, EZ-PD Config Utility doesn't launch.

Is it possible to use it without connecting the evaluation board to the personal computer?

We are using the PMG1-S1 in a product and need to access the internal ADC to measure external voltages, according to the datasheet the ADC can but none of the Modus Toolbox examples allow access to the ADC in the "Device Configuration" -> "Resources" tab.

If you have a project that uses the ADC in the PMG1-S1 please point us to it.

Thanks

We are develping CYPD3177-24LQXQ in a design and because there is no footprint recommendation in the datasheet 

Could you please share the document for recommended footprint.

Best regards 

Hi, 

I have a design with two 6227 PD controllers that are connected to 4 type-c ports. I would like to select the sink path to be active on one of the 4 ports. 

Reading through the Host processor interface, there does not seem to be a good way to do this over i2c. 

Specifically I would like to handle the following case as an example. 

1. 60W PD enabled monitor is attached to controller 1, port 1 allowing charging from the monitor.

2. Later on a 90W PD charger is attached to controller 2, port 2.

In this case I would like to have a way for the EC to disable the sink path on controller 1, and enable the sink path on controller 2 when the second charger is attached to make use of the higher power. 

From the interface specification it seems I would have to update the allowed port role from dual power role, to provider, however this would require issuing a port disable command first, which would disconnect the monitor alt mode. 

How can I disable the sink path fet via the HPI interface without resetting the port and causing interruption to the data role? 

您好：

如果客户需要实现对外实现5V/3A对外设充电，同时作为data role 仅需要实现UFP。

请问这种UFP(data role)+source(power role)使用3171通过配置Configuration Utilitys能否实现？

如果不合适，是否有更好方案或者芯片推荐？

谢谢！ 

Hello,

CCG has two FW files (cyacd).

In SDK 3.3.1, ONE and TWO FW sizes are different.

Also, when performing File comparison, the data after Config Table data is completely different data.

CYPD3125-40LQXI_notebook_one_3_3_1_2010_0_0_0_nb.cyacd : 89KB

CYPD3125-40LQXI_notebook_two_3_3_1_2010_0_0_0_nb.cyacd : 145KB

In the previous SDK Version, it was the same size.

When I compared the data, it looked like the same data.

CYPD3125-40LQXI_notebook_one_3_2_1_1658_0_0_0_nb.cyacd : 131KB

CYPD3125-40LQXI_notebook_two_3_2_1_1658_0_0_0_nb.cyacd : 131KB

Q1) Why is the file size different in FW of the new SDK Version?

Q2) Why does the data look different in FW of the new SDK Version?

Best regards,

Kenji Takahashi
