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.

A bit beyond my skills. That is good stuff. If I have a load of 20 amps then with a. I’m using the Dalls 1 wire temp sensors for the two heater temp channels and the DHT22 for ambient temp and humidity.

Last edited by Garbz; at I am working on a project in which we are using a LMP Oh well I guess not. So much simpler than dealing with low-value shunt resistors. Overshoot and ringing are a side effect of a crazy fast switching response which is usually the result of wanting to waste as little power as possible in the MOSFET.

Some of the development boards I have a super powerful and nice to program plus unusually cheaper than Arduino. Simply adding 2 doubles takes around instructions. So the best platforms are high speed 32 bit processors now.

I understand the issue more clearly, for sure. One disadvantage I found which will have an affect more on Arduino platforms is the integer based calculation quickly use up 8, 16 and 32 bit integers. While these are low on rds there are no small packages for this family. I need to get to the bottom of pwm frequency – resolution seems bd170 explanatory.

If the load get to high, I would shut the ouput down.

This may eliminate the ringing even without a snubber. I will consider this as a possible option after completing this semester. The All Things to All People controller.

Gs170 few options are writing a subroutine with a series of delays, or using one of the pulse width modulators with a really slow clock cycle which can always be slowed down further by counting in a loop i. A double is still a float, just a double precision float is 64bits long instead of 32bits. AndrewJ Watch me post! fiiletype

Cant think of the part number at the mo but I’ve used in the past and work well up to 60amps. Hi Garbz, On my tiletype, a 10″ LXGPS, I have the dew heater just behind the corrector plate which appears to be the best location, and the idea is that the heat going into the tube and slightly heating the back of the corrector plate, airstops the dew from forming on the front.

Also some plastic RCA connectors have exposed parts of the shield. Power dissipation is critical as I was targeting a SOT package. Up to 30A in an SO-8 package. Find all posts by Garbz. Very nice project Chris.

I generally use bs710 output stage Mosfet RdsON as the shunt Should be trivial to change: I was amazed the amount of code required to do floating point calculation compared to integer based calculation.

Alain PS ; and like that??? Also I’ve decided to drive the relays via an I2C port expander. This may not work.
