Micro / Car / Power problem

TKS said:

Hi all,

i have a problem in a micro project.

the problem is that i hookup the micro to the battery of my car and while i start the car, the micro shutsdown / goes of..

when the power returns it doesn't switch on...

i need to do a reset / mclr pin to have it ready again....

are there any fuses who might help or what kind of circuit do i need to make / wich components to use soow the micro gets voltage while starting.

hope you all have ideas and share them

Regards,

TKS

Can give me an example of an:

"reverse blocking rectifier, and have a LARGE electrolytic on the input to the regulator"

An electrolytic isn't the same as an elco right? wich value?? 470uF,2200uF

If i get you,

You want to do this trick

You want to load the capp and the power it unloads can only be wasted/usted bij the 7805?

So in my case i also use some servo's, they are connected to 7806's
(2 in parallel with heatsink)

soow i noot to connect them behind the diode 2..

the sheme is like it is now...

Hope you can help a bit
