lots of ideas to tease my imagination today.

Iron

hello all from Edmonton, Alberta. getting closer to doing this in real time.

Iron

Thanks warren, its very informative

Platinum

excellent narrarion from an expert

Platinum

very understandable

Platinum

Power management by FPGA/cpld

No experience with analog designs

better late than never.

Iron

it had been no synchronisation between audio and video from  the presentation why?

Iron

Alaskaman66- Some good questions.The Platform Manager uses the current sense circuitry and the on-board FET to sense and control current onto the board. If the spikes are long enough it can easily manage board insertion/removal events. All timing is programmable- ramp rate too. Energy storage needs to be done external (super cap maybe?).

The Power to You book is a great reference and should be able to answer your questions in precise detail. It is available for free here.

Iron

thanks sir rob and sir warrren, i am enjoying reading all ideas in the post...thanks to all colleagues...goodnight.

Thanks everyone for attending today's program. Come back tomorrow for Warren's third presentation.

With the Lattic platform manager, I have some questions. On board removal, does the LPM mitigate any voltage spikes, say from an inductive or capacitive load? Is there any sort of sequenced regulator turn off or energy storage capability, to make sure, for example, that the MCU is the last thing to lose power and has time to do POST? Also, does the FET switch stay off until the 12V bus stabilizes upon board re-insertion? Can the LPM monitor input voltage or current and disconnect via the FET upon seeing excessive excursions in either input voltage or system current? Are those parameters programmable?

Thanks everyone for the questions. Here are the links to the references for todays talk.. (PPT links are not working).

Iron

@Alaskaman66- And the comparitor settings are usually dynamic so they can be changed based on a stae machine or controller output... I think the PSoC devices are the most flexible in this regard..

Iron

@Alaskaman66- The comparitors can typically be set to fairly precise levels. Some devices have automatic windowing functions to so you can tell if a voltage is 'out of range' prior to sending an interrupt to the controller.

Iron

Alaskaman66- MCUs tend to have a larger number of bits and better conversion times (since the try and target audio applications and above). The devices covered today are more targeted at sensors and slower applications like that...

Iron

Can the degree of hysteresis be programmed? For example, the temp span on a heater control between state changes?

MazianLab- By high power I mean circuits at 48V or a bit above (like LED strings). This is high power relative to the 3.3V digital logic. Not high power like KilloWatts...

Iron

Do the A/D capabilities exceed those usually available on a dedicated MCU?

Blogger

Could you explain more about high power systems plz?

Blogger

RMenon- Yep zapping is not good. Why I'm a digital engineer not an electrician...

Iron

ok, sir warren...thanks.

but usually in high-rise buildings are low voltage, maybe in other applications.

DouglasEaton- I'm stuck using a PC for my hardware projects too. I wish the Mac was better supported. Running in emulation mode might work- I have not tried it... Larger FPGA devices would probably be a problem however..

Iron

Thanks Warren.  I guess high power is one where you get zapped when you touch the live terminals!

Iron

Ronaldgomeseria- Which Rockwell devices do you mean?

Iron

@Alaskaman66- By high voltage I mean more like 48V not 120VAC. These devices can't (yet) do much in the AC space directly. They would need external devices/issolation...

Iron

Alaskaman66 - thanks for defining high power.

Iron

the fact is, that's the first time I saw about lattice platform manager...is there any difference using rockwell?

@ Ronaldgomeseria- The PSoC5 is probably best for gneral buildin control that don't require high voltages. If you have motors or solenoids that require high voltages the Power PSoC is probably better.

Iron

Thanks, good presentation, Confirm good products Linear devices, Maxim and TI on board level power managemnt and sequencing

Iron

Thanks Warren; I've already passed this slide set to one of our analog designers.

Back for more tomorrow!

 

Iron

tomorrow i can't be able to attend because of our meeting at ASHRAE Oryx Chapter as one of the member of the BOARD OF GOVERNORS...But still, archive is there I can have a look and attend maybe before on the 4th day class...

thanks once again sir warren and sir rob...

Cypress PSoC 5 web page:is here

Cypress Power PSoC is here

Lattice Platform Manager is Here

Iron

By high power control, are you basically referring to switching voltages above the supply voltage for the chip? Say 120 VAC or 48 VDC? I  imagine a high current (power) aplication would still require an external device, such as a solid state relay.

Cant wait for tomorrow

Iron

Thank you Warren. Great presentation. 

Iron

Most power supply stuff done with Linear Tech parts, LTSpice and great support from LT

Iron

What is the difference with the building management controls with the lattice platform manager?

Blogger

Does anyone have any experience programming devices using MacOS in stead of windows.

Even if it's using Windows in emulation on the Mac.

 

 

Blogger

anyway, thank you all and especially to our dearly lecturer unto this class session and to sir rob as well as digikey and design news for CEC initiatives.

Warren, thank you for today's presentation

Iron

Warren - great presentation.  Rob, Thanks for keeping me on track with the slde numbers - came in handy as I kept rebooting the presentation to hear the audio = tomorrow I will hard-boot with my work boots on! :-)

Iron

Thanks very much Warren and Rob

Iron

Lots of info. Thanks, Warren

Thanks Warren and Rob for the series

Iron

Looking forward for the next lecture

Iron

Great lecture. Thanks.

Blogger

Warrren I have done analog in the past such as hi power RF P.S. but my focus has been primarily digital and yes, I know, there are no digital circuits.  I have been more on the software side lately.

Thanks
