USB EZ-PD™ Type-C Forum Discussions

Hi,

Looking at ModusToolbox I don't see an Alt-Mode DisplayPort example for CYPM1211-40LQXI, but as this is one of the highlighed use-case mode at it's product webpage, I'm wondering if there is any example code that can be shared?

Best Regards,

Hi there,

I have few questions about PMG1-B1

1. Can PMG1-B1 use to be powerbank application, DRP (source/sink)?

2. SDK support battery 5 cells BMS?

3. Is there ref design and EVB supports in this moment?

Thanks

I'm repairing a Dell laptop with USB C charging. Visual inspection revealed CYPD4126 was burnt and pins 12, 31,32 and 33 were shorted to gnd when tested isolated from the board. I replaced with a new chip and the laptop does not boot charger voltage stays at 5.08V, 0.02A. Does this chip need firmware to negotiate the power delivery? Can I flash it using the laptop? Would I need the specific Dell charger for it to work properly? Your assistance will be much appreciated, thanks in advance.

Hello.

I'm evaluating CCG7S for car charger application.

There was about deadtime in datasheet like below.

'In addition to drive strength, the high-side gate driver and the low-side gate driver have programmable options for deadtime control and zero-crossing levels.'

I tested to change define macro but deadtime is no different.

#define BB_GDRV_HS_DEAD_TIME_NS (0u)//default (10u)

#define BB_GDRV_LS_DEAD_TIME_NS (0u)//default (10u)

Let me know where can I change the code.

Regards.

Is it possible to use CCG4/5/6 for Charge Through Dongle

can you supply the all necessary code HPI/i2c for a power adapter pass through advertisement

we will be powering device from any of the shelf PD Capable power adapter High power up to 100watt 5A 20V PDO capable with e marker cable connected to one of our ports on CYPD622796  and our circuit will be taking approximately 5-8 watts of power  for our small circuit (sorry not able to give all info out what this gadget will become) and advertising the rest as available modified PDOs on the other C port that powers to the laptop... we are looking to make it ultra compact boards space of no more than 12x10 mm for entire circuit hence need a dual port solution IC

ideally we would want either port to be the power adapter cable port and simply do a DRP swap and auto select sink port based on connected device and make output automatically for the other C port 

CYPM132x-97BZXI

We need to steal some power from C power adapter

Need help with a simple pass through dongle design with SINK and SRC port but the SRC is only a re-advertisement of the SINK less a few watts that we will be sifining out of the PD profile

Looking for details on how we can request Power Brick PDos wrap them up and send it to a SRC port using dual port IC to save space 

any examples of code that does this task are greatly appreciated 

I have designed the Schematic for EZ-PD™ BCR with the help of its datasheet and CY4533 BCR Evaluation Kit. I made this design according to 12V/5A fixed output and no firmware control required. datasheet was bit confusing for me so I want community's help to review my schematic and point out any issue if they find any. I would be thankful for your assistance. Also there is one additional question that this highlighted 5V_Safe line can be connected to external circuitry or its just for testing purpose. Kindly help. Thanks

Hi,

is there any setup required to get SAFE_5V PFET enabled? When connected with 5v USBC or USB A, the gate driver is 5v (PFET is OFF). 

I2C PD_STATUS bits:

UsbController.cpp: 59: onStatusTimerExpire(): VBUS voltage is 49
UsbController.cpp: 62: onStatusTimerExpire(): BCR_CFG=0x0 DATA_ROLE=0x0 POWER_ROLE=0x0 CONTRACT_STATE=0x0 SINK_TX_RDY_STATUS=0x1 POLICY_ENGINE_STATE=0x1 PD_SPEC=0x2 PARTNER PD_SPEC=0x0 UNCHUNKED=0x0

Please let me know what information I need to provide.

Regards
