It's new for me to actually ask a question here instead of only reading which I did appreciated a lot in college. I have a background in mechanical engineering and do have some (low level) experience with electrical engineering. Currently I'm stuck on what looks to me a pretty simple circuit.
What I need for a project is a CR2032 powered LED that has two modes -> solid and blinking. It has to cycle through these functions by using a single switch. The first time the switch (sort of toggle switch) makes contact the LED is powered ON solid. If the switched is released again the LED starts blinking for 3-5 seconds. From that stage I would like to have two options either it completely switches OFF after 3-5 seconds or in the case the switch makes contact again (within these 3-5 seconds) the LED remains blinking. Switched OFF again and it stays OFF.
I've done quite some research and I've seen similar systems using a 555 timer. However the most simple solution I've found was a small bike light sold here in Amsterdam. This system only has an IC, two resistors and a capacitor -> LED series resistor and debounce. It is powered by two CR2032 in series. As this is a battery powered bike light it must also be energy efficient and cheap. Unfortunately I cannot find anything about the 5 legged IC (TS6536B) on the internet. So I was wondering how this works and if I could use anything similar for my project. Any help on how to find the specifications of this IC or how to approach my design in general would be greatly appreciated.
