Time based control

[udhaya]

Hai friends,

I want to on and off the input voltage(like 12v to 24 v) based on the time like 1.3minutes on and 0.30seconds off the supply voltage(the time of on and off should variable i.e adjustable), let me know the sample circuit or solution for that.

Please help me on this thanks in advance.

Thanks for the feed back, also i want temperature based control if temperature reach 75 degree cut off the input voltage and temperature decreases to 45 degree turn on the input voltage, i want to maintain the temperature in between minimum40 to maximum75 degree,please send me the circuit if available

thanks

The same chip can be configured as a temperature control.
Look at the link I provided.
