Can i use 555 Timer IC OR any other equivalent IC for generating Alarms / Sirens within Smartphone wireless device ?.

Awaiting your reply,

Thanks & Regards,

Answer
Not sure I understand the question.

- Do you want to incorporate a 555 into your smartphone?
- Do you want to use the voltage from a smartphone to power the 555 timer circuit?
- Are you looking for a compatible equivalent IC to the 555 that does not draw so much power?

If you are thinking to put a 555 inside a smartphone I think you will not find any room as these phones are very compact.  If you are looking for a lower current device than the 555 there are many that you can find on google.  See this version, for example:

Hope this helps. Let me know more what you want to do.
