PC power on/off switch controller circuit
I'm looking for a simple PC power on/off controller circuit. The standard PC power supply provides +5VSB but all my digital logic runs on +3.3V. The PC front panel switch is a momentary switch that is used to turn the PC by pulling the power supply PC_on# line low and holding it low until the momentary switch is pressed again. Is there a circuit / power management chip available that can perform this function already available, or do I have to get creative?
Thanks for anyone's help in advance!!!
I think you'll need to get creative. It sounds like a simple flip flop circuit. Good luck
Can it be possible to create a device which comes with a timer which can power on my PC at specified time?? Now when I want to on my PC I have to push the power button, I just want a device which can do this ,"push the button work", or connect the circuit of SMPS at a specified time!!!! Is there such SMPS with timer on is available for PC in the market????
I have a net connection which have a unlimited download period from 2 am night to 8 pm morning and I don't want to wake up only to push the button and also I don't want use any software which wake my PC from from hibernation!!!! I want to automatically start my PC at a specified time from total power off situation!!!! If any such SMPS available for PC then please let me know or can I modify my SMPS with the help of any circuit??
If you understand what my query is then reply!!!!
I know of another vendor besides TI that makes some of these - try a web search of 'push button controllers'...
