Abstract:
A latchup protection and recovery circuit device for protecting and recovering a protected electronic device from single event induced latchup, which comprises:(a) means for sensing the supply current of the protected electronic device, the electronic device having inputs and outputs;(b) means for switching the supply current of the inputs and the outputs of the protected electronic device to an off state;(c) means for determining when the sensed supply current indicates the presence of the single event induced latchup;(d) means for controlling the switching means to place the protected electronic device in the off state, the means for controlling being responsive only to the determination that a single event induced latchup exists;(e) means for timing the switching of the supply current, of the inputs and the outputs of the protected circuit, so as to return the protected device to it's operating state; and(f) wherein said latchup protection and recovery circuit device and said protected electronic device are within a single integrated circuit package.
