I'm looking for an equivalent for the MAX6433 battery monitor. The datasheet is here:
**broken link removed**
This specific IC asserts its output when the low voltage threshold is hit, and disables the output when the higher voltage threshold is reached. I'm looking for an equivalent in a...
I'm building a simple circuit that uses a couple solar cells to charge a (huge) capacitor. I'm using four solar cells, rated at 3V/20mA, in parallel to charge a 22F capacitor (I am aware the capacitor is huge, but this is a purely educational exercise). I use a 1N5817 Schottky diode in series...
Thanks for your input. I will try to get the 14 pin version soon.
I am curious, did I wire the reed switch correctly? When the switch closes, doesn't the current go straight to ground? How does the LM2917 pick up the signal?
I posted a thread about a lower power anemometer here:

I followed the steps outlined in the Easter Egg Anemometer site, however I am having some trouble with the LM2917 Frequency...
Thank you Matt, can I get a PM with more information regarding that?
I found this circuit while searching online:
**broken link removed**
This circuit seems to be almost exactly what I want (basically the analog voltage output), except that the given values for R1, R2, and R3 only...
For the design, I am now able to use a 5V voltage supply. I decided to use a dc-dc step up to get from 3V to 5V to facilitate the design. I found this:

It seems to provide everything I need: factory calibrated, analog output, and low...
Thank you for all your input.
However I'm sorry, I forgot to update my original post. This anemometer that I am designing will be used inside air ducts within buildings or houses, hence the very small range of wind speeds. I won't have to worry about natural, outdoor corrosion or related...
Thanks for your reply.
The output should preferably be a DC voltage. I'm interfacing this anemometer with another device, and the most ideal situation for me would be to "poll" the output voltage at any given time to obtain the correct windspeed (after doing calibrations).
I forgot to add that...
Hello all, I am in need of some design advice.
I am designing a low power anemometer. The main hurdle here is that I can work with only a 2.5V supply (with 3V as the absolute maximum because I am running on 2 AA batteries). Also, I need to have a voltage output. So, if I were to look at the...
