USB EZ-PD™ Type-C Forum Discussions
I've been trying for hours to get the CCG2 EVK to supply any voltage to an attached BCR board.
What am I doing wrong? I added PDOs for 5V/3A, 9V/3A, 15V/3A and 20V/5A and connected TP17 to TP20 as well as TP18 to TP21
I notice that the VBUS voltage jumps between 5V/9V/0V but no connection is possible.
Show LessDear Cypress Community,
I'am contacting you from Erlagen (Germany), so please excuse my poor english.
I developed a simple USB-C PD source cuirquit following your Reference desinge ACT4751-101 closely. But I stil have some remaining Questions about the USB-C controler CYPD3171-24LQXQ that my cuirquit will be using.
I hope you can help my with that.
1. Does the CYPD3171-24LQXQ come with a preconfigured Firmeware running on it? If yes what are the values of the PDO's in this preconfiguration?
2. Which Programming Tools are able to use your EZ-PD Utility to change the the Firmwareconfigurations on the USB-C controler? (Is it only possible with the CY4532 EZ-PD CCG3PA Evaluation Kit? Or does the CY8ckit-002 Psoc MiniProg3 also work for that?). Both of them seem kind of expensive, so are ther any cheaper options to config the CYPD3171-24LQXQ?
3. In the Reference design you are using the Qurvo ACT4751 as dc/dc converter. Do I need to reconfigure that one aswell or schould both chips be able to comunicate right away?
4. Are there any Reference-Codes for the Firmeware of the CYPD3171-24LQXQ available that would work in an application similar to the ACT4751-101 reference?
Thank you in advance for your help.
Yours sincerely
Sebastian
Show LessGood afternoon, there is a 20V 60W power adapter project. We want to buy the CY4532 EZ-PD, only there, as I understand it, you can use a maximum of 12V, is there an opportunity for a test to supply externally 20V power? power is not important for tests. thank
Show LessHello,
I'm using the CYPD3177 BCR Kit. I experience different behaviour of the DC_OUT port (controlled by P-MOSFET / VBUS_FET_EN) when I'm either using a PD capable source (PDO 5V 1A) or a 'simple' Type-C source (10k pull-ups on CC lines to 5V -> 5V 3A). I can read the PD_STATUS and the TYPE-C_STATUS registers via I2C. As far as I can tell the port controller detects the type-c source correctly (port is connected, source is attached, Rp of partner device suggests current level 3A, etc.).
With the Type-C source the P-MOSFET is activated rather late. We are talking about approx. 3.5 seconds between making a connection and enabling the output.
With the PD capable source the output is at 5V rather quick (< 1s).
What are the conditions for the CYPD3177 port controller to activate the MOSFET / the power output?
Is there a difference in decision making or with the timings based on the power source?
Best regards
Alexander
Hi,
I have checked CCG3PA, Datasheet it supports BC 1.2 charger detection, Actually I am looking for BC 1.2 Charger advertisement, Do cypress have any IC that support BC 1.2 source mode. If yes, Please can you suggest the IC/DVK that I can use for my custom design.
Thanks & Regards

Show LessHi,
I am using CCG3PA IC(CYPD3171-24LQXQ) in my application circuit, I am trying to program the chip with Miniporg 3 in power cycle mode by giving supply to chip from Miniprog3 but it was unsuccessful(please refer image below)
but when I try to program the same chip by keeping in Reset programming mode and by giving power supply from board and used miniprog to program, with this setup the FW is getting updated in IC.
but as per datasheet the CCG3PA is not supported for Reset mode programming.
Please let us know why this behavior is observed and what changes need to make it in power cycle programming mode,(refer my circuit)
J1 is connected to 2 and 3 pins in power cycle mode, where J1 is connected to 1 and 2 pins in reset mode programming
Thanks in advance
Best Regards

Show LessI'm interested in using CY4521 evalkit. However from looking at the schematics I don't understand how the CCG2 communicates the source voltage setting to the DC/DC on the base board. The VSEL lines are not connected to the CCG2 anywhere?
Show LessIf I plug in a CYPD3177 to a legacy Type-A charger, using a USB-A to USB-C cable, how does the CYPD3177 behave?
1. Does it attempt to verify current capability using something like BC 1.2 and the datalines?
2. Or does it simply ignore the "Power Delivery" aspect of the design and simply pass the "legacy" 5 V through to the system?
3. Does the undervoltage detection still work with legacy charging: "FAULT is driven to Logic HIGH if ... Voltage on VBUS_IN is 20% below the VBUS_MIN setting or 20% above the VBUS_MAX setting".
The reason I ask is because I have a design where legacy Type-A 2 A chargers are sufficient to power the design. I want to know what would happen if the user was to use these kind of chargers.
Similarly, how does the device act when connected to a USB-C only device(i.e. no PD functionality)? I similarly would like to know what would happen if the user was to use a 5 V @ 3 A non-PD USB-C charger.
Show LessA project I am working on uses a battery that runs from 29.4-22.4V to run their equipment. We would like to add a USB Type C port with PD to it as a source (NOT A SINK, we will charge using another method) for a Laptop with a USB-C PD port as a sink so that it can charge when the laptop battery is low. What CCG kit would help me to get started on this project?
