Patent attributes
A burn-in apparatus for burning MAC address stored a burning machine (100) onto an IC (302), which includes an isolation circuit (220), a voltage switching circuit (230) and a power switching circuit (240). The burning machine, the isolation circuit, the voltage switching circuit, and power switching circuit are serially connected and form a data transportation channel. The MAC address is transferred to the IC through the data transportation channel. The isolation circuit prevents interference between the burning machine and the IC. The voltage switching circuit supplies a high voltage to receive data for the IC to be burned. The power switching circuit supplies a working voltage for the IC. Finishing of the burning, MAC address returns to the burning machine through the data transportation channel.
