| Abstract: | A novel LD driver controlled by single-chip microcomputer and FPGA is designed,which achieves over-current protection by taking count of spillage,and it can effectively eliminate the interference of large current with great pulse width,and has functions of avoiding wrong judgment for over-current and disabled protection,so it makes LD to run continuously and reliably. |
