Method and apparatus for providing hot plugging protection for laser optoelectronic devices |
摘要 |
A method and apparatus for providing hot plugging protection for a laser optoelectronic device in a laser driver and fault detection circuit are provided. The power supply voltage is compared with a defined threshold potential utilizing a power on reset (POR) circuit. Responsive to detecting a power supply voltage potential below the defined threshold potential, an output control signal is generated. A current interrupt laser driver control signal is generated responsive to the output control signal to interrupt the laser driver current. A clear fault control signal is simultaneously generated responsive to the output control signal.
