thanks a lot .. the problem was that audioguru mention .. ground wire between l298 voltage and 5v .. in my last one pcb there is connection between two ground but in new one pcb the track was clear from protel pcb " I dont know why or how? " ..

i have very sensitive rf module in circuit ( i don't draw that in schematic ) and when i use one bridge rectifier instead of two bridge rectifier just like audioguru's schematic , when motor run the module doesn't work so i use two bridge rectifier ..

thanks all for your replay
