Granted: 2001-05-16
Abstract: The protection circuit of this invention has the functions of automatically turning-off and recovering electricity, in which device will not be burned out when the protecting action is performed. The protection circuit and the drive circuit of cold cathode tube are linked together with the whole drive circuit through the voltage value generated by a capacitor. When the load of drive circuit is high, the transistor of the drain circuit switch controlled by capacitor makes the capacitor charge to the threshold voltage of transistor so as to conduct the drain circuit and lead the current away from system. When system recovers the normal operation, the voltage of capacitor is made to decrease in order to close the drain circuit again such that a kind of protection circuit can be achieved by using non-destructing device manner to protect system and has the ability to automatically recover electricity after the load is normal. Therefore, this invention possesses the advantage of not destroying device.
