## Abstract

Energetic firing device using a boost circuit to ensure an energetic fire circuit is charged to an All-Fire voltage even if a power source is not capable of providing necessary voltage. Boost circuit may be located between power source and energetic fire circuit and increase voltage provided by the power source when enabled. Boost circuit may be located between system logic and the energetic fire circuit and generate the All-Fire voltage when enabled. The boost circuit may generate the All-Fire voltage from an enable signal and a pulse train provided by the system logic. The boost circuit may be a switching power supply that may regulate the All-Fire voltage generated. The boost circuit may be a capacitive voltage multiplier. The boost circuit may remove power from being provided to the energetic fire circuit until enabled thus reducing system power and increasing safety.
