i have a circuit that uses pwm of atmega 8 and the power bridge of l298n ,to power a dc motor
but when i connect the vs voltage of l298n ,the micro stops working
i used even used seperete power supplys but the same result
any help would be appreciated
 

Hi,

Think you need to show your circuit diagram with power supplies as it should work ok; everything is connected to the same common 0v rail ?

You have got the L298s Enable pins wired correctly ?

When you say the micro stops working, how does it stop, no pwm signals or loss of power or the lcd screen goes off ( if used) ?
 

hi

enable pins and gnd rails are checked
micro stops working, pwm stops,and it no longer respond to any input
