UCD9090A: How can I simulate or test my UCD9090A Configuration developed in Fusion Digital Power Designer?

Part Number: UCD9090A
Other Parts Discussed in Thread: UCD9090, UCD90SEQ48EVM-560

How can I simulate or test my UCD9090A Configuration developed in Fusion Digital Power Designer?

I am thinking of using the UCD9090A perhaps in a board design. I've setup the configuration and everything, but need a way to test it, even if it is just a simulation. Basically, I need to ensure the IC responds to faults and creates them the way I expect them.

Also, what would I need to connect the IC to a PC using the I2C bus for programming etc? 

Basically, I need help developing this sequencer and was wondering what would be the most efficient way to get this done.

Thanks,

Vinny

    Hi Vinny

    Once you have the configuration developed in FusionGUI, please order UCD9090 EVM(http://www.ti.com/tool/ucd90seq48evm-560 ) + UCD9090A(http://www.ti.com/product/UCD9090A/samplebuy samples so that you can download the configuration into the a live device and play around the device.

    Please also order USB-TO-GPIO Dongle http://www.ti.com/tool/usb-to-gpio  which allows EVM to be accessed from PC.

    Ok thanks, what if i want to include a header on my board design to program the UCD9090A via I2C? The USB to GPIO dongle has a 10 pin ribbon cable while the dev kit has a 14 pin header for JTAG. What header part would I need on my board?

    Yes, a header(10pin) is highly recommendand ed and convenient on your board to connect with USB-TO-GPIO Dongle. So you can communciate with the device from PC. A 14-pin header(from whatever dev kit) will not work.

    if due to space limiation, a header is not fitable, you need as least SDA/SCL/GND to wire out.

    Hope this helps.

    So from doing some research, the USB-GPIO Dongle has the following 10 pin, 2.54 mm pitch, unshrouded header from TE

    The 10 pin cable with connectors on the USB-GPIO Dongle is part number 

    • M3DDA-1018J

    A similar 10 pin vertical header from TE is part number

    • 87215-2

    Do these headers seem like they would work for the application?

    Finally, so I have to pay like 175$ just so I can test the IC for my application, no other way around this? If I get the board, do I need to interface all my rails to it in order to test or can I just test the GPIO sequencing without voltages being present on the monitoring pins? Would I be able to create software faults to test all the sequencing scenarios?

    Thanks,

    Vinny

    Hi Vinny

    If you are using TI 9090A EVM(UCD90SEQ48EVM-560), there is no need to order USB-to-GPIO dongle since the EVM has the built-in dongle hardware.

    But if you want to communicate 9090a on your own board, usb-to-gpio adapter is required.

    86479-3 is the right head and ribbon cable come with adapter from TI..

    We do not recommend use vertical header since you may plug the cable in a wrong direction.

    Awesome, thanks for the clarification. That about answers this thread.
