I am working with Li batteries for 2 years.
Use battery in parallel or series is very dangerous
You need pay attention for the definitions about your project for avoid problems in future.
How many cells you will use?
Which is max consumption of the circuit?
The battery will be removed of the...
Hi people,
I need help to project my gas gauge.
My device have a li-ion battery, 3.6V 800mAh, it uses MCP73831 and I have no problem to charge the battery. But I need inform with precision to operator that the battery have more 30 minutes of life.
For this I want use LTC4150. But I´m not...
ahhhh, now I get the 0.7V you commented. This isn´t a problem.
About for the resistor between the transistor and capacitor, should be for limit the amount of current, not polarization.
Your circuit is more simple than mine so I will test it first.
Yes, yes, I know how calculate. t=RC, but when I have a transistor in the output capacitor must not be so simple.
Well, I´m looking a simplest solution, for this I thought in RC. I don´t need precision in delay, need only start a uC, after, uC can maintain the transistor working.
Edit: I need...
Happy new year for all.
I´m a little problem in my project.
I have a transistor (BC817) working as switch, but I need a little delay in your output.
For exemple:
When it allow current flux and the base goes to low state, I need it hold on flux for 0.5 second or 1 second.
I´m thinking in use a...
Good morning guys,
I´m with problem with TMS3705 from Texas. This a Transceiver IC and I can read tags but the distance is very short.
Using the oscilloscope, I saw that antenna signal is very low (+/- 10V peak to peak and should be > 40V).
I did my antenna when the datasheet, but I´m whith...
