I'm going to build two. One for my 3.7v mod and one for my 7.4v mod.Question. Is the TL431 the same as the LT431?
Quick question about the pins on the TL431. Are the pins as shown in the schematic as follows?1 = anode2 = ref3 = cathodeThanks
Hello guys,I was searching for a circuit to monitor the battery voltage....i've read this post i't's excellent, but i was searching for circuit that could do something likegreen - full ...... green/red - medium ....... red - lowmaybe with a bicolor red/green led...Someone has any idea???Thank you to all
Power consumption says 5mA which is current not power, but if it's 5mA and not 5mW, that's a bit high to leave on a battery full time. Probably okay for removable cells, but not for permanently mounted cells. If you were to leave your device lying around for a couple months, it would over-discharge the battery.
You could Tie that LED output to a MOSFET to switch battery power.
There are two circuits. They are making a combination of parallel and series. On looking at these circuits we can realize that at least 1% tolerance and low wattage like 1 to 6 watt is require. It may vary with time.
I found it!That's what i was looking for...Do you think this will work???
Why 2 LED's? Sorry I can do basic wiring and soldering but all these LED's and resistors make my head swim.
