L6235 current control

Hi i have a problem regarding the L6235PD. With the EVAL6235N everything works fine. Problem is my own PCB layout. The monostable never triggers the bridge off and the motor consumes a lot of current compared to the eval-board circuit. I used all the information from the application note but there must be some error in my pcb. Is there anybody who could help ? I could provide the schematics and the board file if it�s necessary.
