The electronic ballasts with IC off function,The MOS gate driver IC (MGD), drives a pair of MOS gate controlled power semiconductor device used in, for example, the half-bridge circuit used in the electronic ballast circuit in the power supply circuit to drive a resonant load or a driving gas discharge lamps. The gate drive circuit includes a protection circuit to protect the components in the drive circuit when the lamp failure or removal by prohibiting the output of the two drives without being damaged. When the lights are back in, the gate drive circuit without the power switch of the lamp to restart the lamp drive circuit. When the low logic level signal falls below the threshold voltage, the protection circuit disables the output of the drive. When a low logic level signal exceeds the threshold voltage, the lamp driver circuit is restarted.
