Hi all,

first post.

I am trying to use a CA3140E op-amp as a comparator.
The two inputs are chemical sensors. The difference voltage between them
can range between 400mV, to 50mV (100% concentration to 0% concentration).

I remember reading somewhere in a text book, that if V1-V2 is greater than
(I think) 100uV the op-amp will go into saturation.

Can anyone a) clarify this for me, or b)suggest a better way to measure
the difference voltage.

Component count is a factor, as is power consumption. (I want my cake and
eat it too!)

TIA

An opamp used as a comparator typically would go into saturation, especially
since you probably want to add a little hysterisis.  A saturated opamp may
take a little longer to respond to different input signals, but that should
still be much faster than your chemical concentration can change.

       Is it possible that the statement meant "if 100uV is applied between
the inverting and non-inverting terminals, the op-amp will go into
saturation"?

       If that was the question, then someone needs to explain negative
feedback :) Certainly, it's possible to use an op-amp to amplify a
differential signal between 50mV and 400mV. Just don't apply that difference
directly to the op-amp terminals.

       Perhaps the problem needs to be explained a little more. Is the
difference between two sensors being measured? or are there two sensors,
whose ouput varies between 50mV and 400mV? What is the amplified output
connected to? what range does the output voltage need to be in?

I started building an observatory with a roll off roof about 3 years ago.
The structure itself is finished.  The roof probably weighs about 2000 lbs
and rolls on steel wheels and while it can be pushed by hand, it takes a far
amount of force.  Not being fond of being cold, I constructed the mechanics
to roll the roof back using a couple of 24v dc motors.  The controller box
uses a 16F877 as the brains.  I am using (trying to at least) to use the PWM
to control the motors with.  The output of the PWM goes to a 220 ohm
resistor and then to the gate of an IRLZ44 (N-channel 60v 50A FET) which
between the motors and ground.  There are a pair of relays that reverse the
leads of the motors to change direction.  I am aware of back EMF and the
need for a blocking diode.  I have a blocking on each relay coil and another
diode between the +24v and the FET.  The FET works the first time, ramping
the motors up in speed, but after the relays switch the first time, the FET
becomes a dead short.  At first I thought the motors were drawing too much
current, so I tried two of the IRLZ44 paralleled - same result.  Anyone got
any suggestions?  I would really like to get this finished.

If the word pictured is not clear enough, I can place the schematic on my
web site.

Thanks to all,

A bit off-topic, but I'll ask anyhow: I have been asked to come up with
a vehicle 'mini-UPS' design, something that takes 12v (car DC) in and
produces 12v @3amp and 5V @6amp out. The PSU must be able to maintain
power for a few seconds when the vehicle is started, and the battery may
dip to say, 8v.

I guess I'll end up with some switcher design & and small NIMH / NICAD
battery pack able to provide a few amps to the PSU input for a minute or
so, but wonder if the listers have any thoughts on this problem? Any
great IC / regulator chips out there that solve this problem?

Thanks, Peter Moreton

Hi Peter,

I think I'd solve the 12V dip with a NiMH. Remember that normally the car
runs at 13.8V or higher, so you could always keep a 12V NiMH pack topped
off except during starting. Since the differential is so small, I'd charge
the Pak in pulse mode, i.e. directly off the raw 13.8v using HV MOSFET
switches. For a 5V supply, there are several choices, but for ruggedness, I
like National's stepdown switchers LM2576. They are efficient and run very
cool at 3A each (I'd split the supply into 2 legs with large Schottky diodes).

Make the NiMH pak easily to replace; even with its small duty cycle, it
will need to be user-replaceable in a year or two.

Just my suggestions.

--Bob

Sounds like a PC power supply meant for a car. Have you seen this:

http://www.bobblick.com/techref/projects/yammp3/yammp3.html

It does more than your requirements, but you can reduce it to what you
need. It'll run at 8 volts in.

Rather than a battery backup, why not just build a flyback or SEPIC dc-dc converter that will work from 8 to say 14V?

Yes, I suppose you are right. So long as the PSU can run OK from 8v, and
produce 12v, it should withstand the sag when the vehicle is started. I
guess I need to breadboard a design and see what works.

Russell McMahon posted a message in reply to a question about this
yesterday or the day before, a discrete solution (2 transistors and a

For an IC solution I like the ON semiconductor drivers such as the MC33152.
Micrel has a 12A MOSFET driver in  TO-220-5 package that looks interesting.
You didn't mention what the gate charge would be or what switching
frequency is required so it is hard to give a better recommendation.

Wouter, I suggest you an european solution: CD40107 open drain circuit
and there is also an open source but I don't remember the name, both
have two gates in a DIP8 or SO8 package, high current, high voltage
drive, with low voltage input.

It's a good circuit. But for safety it is a very good idea to also
place a zener diode from FET gate to ground (cathode to gate).
Physically mount it as reasonably close to the FET as possible. This
shunts stops capacitively coupled transients which are injected into
the gate from the drain via the Miller capacitance. It also helps
stops gate ringing -  a whole black art in its own right. I have seen
circuits that run forever with this zener in place but die in minutes
without it. Zener voltage is slightly higher than the V+ gate drive
voltage.

For faster switching place a small capacitor in series with the base
drive resistor on the left hand transistor (not shown in your
diagram).

Very neat circuit.

Anyone have a similar circuit that could be used for the high side
driver in an H-Bridge running at say 200V? PMOS and NMOS high side

  But also then then the 10 ohm resistor must be increased or the V+
voltage must be very carefully chosen. BTW, why such a small resistor
when the gate ON current is quite small ? How large is the gate-source
parasitic capacitance of this FET ?

The comment requesting the CAD package is important.  Usually, in any CAD
package you can pick a similar part and edit the part to make one with the
footprint you need.  Also, you can look at the manufacturer's packaging
specifications and dimensions and use the drawing tools to draw it and save
the file by the name you choose.

I'm experimenting with analog switches/muxes ('4051 and '4066)--my first
time. When selected, the resistance of all switches is as expected, <150
ohms, but when control signal is low R varies from 20-50K among channels,
always way lower than spec. If power removed, all channels' resistance is in
spec.

My first thought was my meter, a garden-variety $20 job, but it seems to be
working fine.

Don,

What is the input impedance of your meter?  If it is less than 20
megohms or so, you'll load the FET down,
And you'll get less than expected resistance.

DevCpp has a setting to develop windows applications. No experience with it, I always use it to generate commandline applications (which you for some reason seem to hate).

I am not sure what you mean by 'use the command prompt', the IDEs I know use a button to launch the application.

Do you mean you want to create a GUI app in plain C?
If so check out Win API, Win SDK (comes with Visual Studio or can be downloaded seperately), GTK. The compiler doesn't create the GUI, it's the code you pass to it (e.g. using Windows API - CreateWindowEx() and suchlike)
Charles Petzold wrote a good book "Programming Windows" that covers the Windows API quite well IIRC.

To the OP: It is not quite clear what you mean. Can you give us an example of what the compilers does and what you want it to do instead?

What do you mean by "run the results"?

Are you talking about the compiling process (writing your program) or about running your compiled program (using your program)?

What do you mean by "run the results"? Run the compiled code? Most modern
IDE can run the compiled code by clicking on a button -- and then you can
get the output in a window if you like.

Or if you need a window based application (GUI as opposed to TUI/CLI), then
you also need to learn a bit of the windowing frameworks, such as MFC or
Windows Forms or VxWorks or GTK or Cocoa -- depends on your
taste, licensing policy, your base platform and whenever you need to
cross-compile your code to other platforms, and of course available tools.
Generally speaking basic stuff such as displaying a string in a text box or
handling an event like a button pressed is relatively easy in all
frameworks. However, each works differently so you cannot easily swap in
between.

Can anyone help me?

I'm looking for a source of desktop universal input SMPSs that will do
at least 2.7A at 24V.
Those are easy to find, but the next bit isn't.

In case of overcurrent, I need the supply to shut down until the plug is pulled.
Everything I have found has "Hiccup mode" or "Auto-Restart" which is
unacceptable.
A supply that operates in this mode could cause a disastrous fire.

There are connector and ratings requirements also, but I will discuss
that with the vendor.
Surplus onesies would be interesting in that they would point me to
the proper vendor to get them from in bulk.

VERY interesting reading:

An interesting article.

I particularly liked the statement "There exists a sobering truth
about today’s electronic assemblies. 100% of today’s
consumer electronics are made without rosin flux (moisture
resistance), use fluxes that do not
“require” cleaning (leaves contamination behind more readily), use
solders that contain no lead
(creates more difficult soldering processes), and use boards that
contain no halides to prevent the
board from burning if a shorting or corrosions event were to occur."

Regarding the original posters problem - how about adding a crowbar
circuit + fuse. Pretty easy to implement on any type of power supply.

Why not add a SCR that fires when it reaches a certain current limit...It would "lock"/crowbar the output until the power supply has been unplugged and the SCR's gate releases. Reading the voltage developed across a low value (.5ohm) high wattage  (5~10W) resistor in series with the 24v leg and firing the gate of the SCR when it reaches your current limit... A few components and a standard (available) 24v SMPS power supply. You would need to handle the turn on surge also.

All good suggestions, IF I could modify the existing circuits.

What I need, is a power supply brick, to replace the existing power
supply brick, that won't keep hammering a failed circuit

Great!
I forgot to put a disclaimer, so I'll add one now:

<disclaimer>I am relatively new here.  Others have much more knowledge and some carry some power.  You'll get to know them in time. </disclaimer>

Sure has been quiet lately.
