Thank you all for your comments and let me make a few comments.
1. 74LVC
For example 74LVC04 is available from Nexperia, TI and Diotec, but only from Diotec is for supply voltage up to 5.5V, others only up to 3.6V with 5.5V tolerant inputs. Diotec does produce the 74LVC04, but not other...
Thank you all for your comments.
In the meantime, I also discovered that the output signal from the STM32 itself has a significant effect on the speed.
I dare not quantify how far the slew rate and how far the lower output voltage 3.3V (the original solution was in 5V logic) contributes to the...
I have a load of 300k Ohm, 50pF and I need to switch a 5V voltage to it using a GPIO MCU, for example some STM32. Yes simple, just a small transistor for example BC847. Yes, it's simple, the leading edge goes from 0 to 5V in about 6ns.
But I would need a 5x faster transition, how to do that?
Thanks
Thank you all for your comments, I will respond to them later.
Now allow me a little reflection, from which I realized what a monstrosity I proposed..
The battery of capacitors designed by me will have a capacity of 3000F at a voltage of 5.4V and a resistance of about 280uOhm if the resistance...
I put my idea on paper.
Yes, I put the transistors and the shunt resistor on the High side. At 5V it doesn't matter, and somehow it seems more natural to have the valve at the top. The rest is actually just a shot of measuring current and voltage plus MOSFET drivers.
It will probably still need...
Yes, these are things I only thought about in the second minute.
The first thing I thought about was measuring the current
- Measure the voltage drop across the transistor as the largest resistance in the chain. Rejected, Rdson varies with temperature if it is 1 at 25C it is 1.5 at 150C.
- Some...
I will need to spot weld 0.5mm Cu wire to 0.5mm brass sheet and 1mm brass wire. Approx. 200 pieces per day, and so I'm thinking about a suitable spot welder or its construction.
I'm interested in this as a reference piece, the price is insane.
Parameters
OUTPUT VOLTAGE RANGE 0.10-5.00 V (0.01 V...
Thank you for the responses.
You're probably right, one extra LDO won't hurt anything
I can only think of what if only +3.3V is available?
Do you have an idea how, for example, the LP2985 3.3V behaves when it has a 3.3V or 3.22V input?
Yes, it doesn't stabilize, I'm concerned with whether the...
I am working on a PCB for a module with 2 to 4 pcs of 19 bit converters for thermocouples MAX31856.
The module will be connected to the processor with an approx. 30 cm cable.
The cheapest and easiest way is to power the entire module from a 3.3V LDO that powers the MCU.
On the module, several...
> Different filter orders
I noticed that too, but I took it from Evaluation Board for the ADE7953 Single Phase Energy Metering IC.
and I was not alone see for example
>Induction in voltage input
.In normal operation (voltage in the order of hundreds of V) you are right.
If a voltage in the...
For a machine with significant electricity consumption, I would like the operator to know how much electricity the machine consumed for a given production cycle
On the one hand, due to the recalculation of costs, and then also, the change in consumption is a function of the wear of some machine...
The original is made of sheet metal and it seems logical to me to do it the same way.
While maintaining the key parameters it could be different, but it has to have the expansion that it holds in other parts.
I thought of a tube with a wider wall or a brass log and a lathe, but it takes a lot of...
I need something like a connector, in reality it is a tube, which has a diameter of 3 mm in the narrow part, 4 mm in the wide part and a height of about 25 mm.
In reality, it is made of 0.5 mm brass sheet. . The connector has a seam, the picture is only indicative.
I need a relatively large...
Don't take it as me disagreeing with you or wanting to argue, no . I'm trying to honestly assess the situation, maybe I'm missing something
There are three solenoids in total
I will place three ARK terminal blocks on the edge of the PCB. I will bring +24V to them, I will want to use a poly fuse...
The designer can influence the max Flywheel diode in this case,
A good one will use fast recovery UF400x
A average one will use universal 1N400x
The wrong one uses 1N4148
Without a diode, he is not a designer, but an idiot.
The quality or political beliefs of the designer will not affect the...
