to filter the list of filenames (or choose a file type from the List files of BS Transistor, TMOS FET switching. Motorola. Q1, Q2. MFBK “Typical” parameters which may be provided in Motorola data sheets and/or specifications . I’m considering either a MOSFET like a BS or a BJT like a 2SC Which would be lower noise I may be just overlooking it when I look at the datasheet but I don’t see it. I’m using a signal File Type: jpg, DSCF Hi there, I’m searching for a complementary low power mosfet pair for File Type : jpg I prefer to match Rds(on) and of course Yfs/Rds from the datasheet. #2 is BS and BS which has comparable small capacitance.

This part is available from both Mouser and Digikey I believe. Some of the development boards I have a super powerful and nice to program plus unusually cheaper than Arduino.

I don’t want to hijack your thread – strictly amateur stuff. The strategy is to estimate the pwm value linearly for setpoint temperature and dither either side to maintain temperature.

They can always serve as a bad example. Cheers Garbz for the heads up on the dew point calc. I would like to be able to monitor the current in to the PIC.


Page 2 of 5. Huh why can’t I edit my original post I still need to test the prox switches, dew controller, and relay drivers. This may cause a lot of heating.

Very nice project Chris. If the devices don’t report in several times a second they drop off and may be forced to reconnect. Find all posts by AndrewJ. The fact you find a double works where a float doesn’t may point to a compiler issue. I am guessing that 60hz is adequate, perhaps less.

Find all posts by redbeard. Only problem is I’m at max ratings for gate switching voltage. Sorry for the long read The idea of putting the temp sensors under the dew straps, I picked up from lots of searches in astro sites looking for commons in temp sensor positions and under the dew heater seems to be the datahseet intelligent things I read.

Another really really cool platform is the PSoc4 platform which as a brilliant IDE that is component based and I believe super easy to develop. An incorrect snubber will simply make it worse. The load can be between 0 and 20 amps. AndrewJ Watch me post! That said a TEC should have considerable thermal mass so you shouldn’t need to switch that fast.

However saying that the commercial straps have metal connectors makes me reassess this. I have a vairaible speed contoller that I would like to measure the current load on the unit.


Warnbro, Western Australia Posts: I’ll reassess and see if I can switch the highside like you suggest with a suitably small package. A correct snubber can help. While these are low on rds there are no small packages for this family. It looks good but it’s not available dataheet my usual sources for components either. I prefer Teensy boards using Teensyduino.

I am sure there are plenty of development platforms out there that are just as good though, but i have too many including Beaglebone Black and other smaller stuff. Also some plastic RCA connectors have exposed parts of the shield. Should be trivial to change: Up to 30A in an SO-8 package.

Specifically as these have the Ishutdown sense. I’ve read also about too much heat as well might not be the best.

IIS member Warren mentioned this a while back but I didn’t get it at the time. Find all posts by rcheshire.
