Hello Friends,
 
Good Morning!...
 
I need help/suggestion from you!
 
Actually I have a device which communicates with microcontroller using the 
serial communication. but sometimes this device stops communicating.In this case 
, this device needs VCC reset( POWER RESET)..So what i want is to reset this 
device from microcontroller  whenever it stops communicating ( basically 
disconnecting the VCC power of this device by turning on some output pin of 
microcontroller  and after 1 or 2 seconds again connecting it)...I don't want to 
use relay logic..so any suggestions regarding the hardware interfacing circuit 
between microcontroller and this device which stopd communicating and need Power 
reset. Current requirement of this device is below 600 mA. and voltage VCC is 
same as microcontroller ( +5V).
 
Thanks a lot!,
 
Best Regards,
Kaps
