Abstract

An electronic ignition circuit may include a logic circuit and an ignition circuit electrically coupled to the logic circuit. The logic circuit may include a microcontroller and a switching circuit configured to switch from a first detonator or igniter to a second detonator or igniter in response to a signal from the microcontroller. The ignition circuit may include a capacitor discharging circuit configured to discharge a firing capacitor through a fuse head. The capacitor discharging circuit may include an ignition switch configured to remain actively closed after the firing capacitor is discharged through the fuse head.
