Abstract

A MOS controlled thyristor is incorporated into detonator ignition circuitry to reduce the physical size thereof, while also providing for ignition reliability enhancement. Signals to either prevent or trigger conduction of detonator ignition energy through the MOS controlled thyristor are applied to the gate terminal there-of by at least one capacitor in the preferred embodiments. The detonator ignition energy is also delivered from at least one capa-citor in those embodiments of the circuitry for use with missile warheads and shunt resistors are connected to dissipate the energy stored in all of the capacitors for safety reasons.
