Hi,
i would like to build a battery voltage cut off when the battery reaches tsh of 11v by using tl431 like the one of MikeMl circuite as in the links below:
http://forum.allaboutcircuits.com/threads/tl431-battery-cut-off.94148/
http://forum.allaboutcircuits.com/attachments/11vdisca-jpg.64658/
Appreciate if anyone can asist concerning a few questions for this scheme/simulation as the below link:
1. What is the meaning of U1 (Rtot=5k) in this circuite?
2. how it is possible to add a hysteresis to this circuite so it will not chatter?
3. how can i make this circuite independent to reset it self?
4. is it possible to add to this circuite an independent Over votage cuttof when it reaches 14.4v using another tl431?
Thanks,
