Abstract

Embodiments relate to fuze setback validation. An electronic setback validator for a launched munition safe-arm fuze includes a transient voltage suppressor. A piezoceramic element is electrically-connected to the transient voltage suppressor. A first electronic circuit is electrically-connected to the piezoceramic element and is a constant 1 milliamp discharge circuit. The first electronic circuit is configured to determine setback magnitude of acceleration. A second electronic circuit is electrically-connected to the piezoceramic element. The second electronic circuit is a constant 122 microamp charge circuit and is configured to determine setback duration of acceleration. A microcontroller is electrically-connected to the first and second electronic circuits.
