Title:
SQUIB FIRING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/063156
Kind Code:
A1
Abstract:
This squib firing circuit comprises: a plurality of upstream switching elements that are connected in parallel to one end of a squib, and supply power to the squib when in an on-state; and downstream switching elements that are of the same number as the upstream switching elements, and are connected in parallel to the other end of the squib. The sum of the on-resistances of the upstream switching elements and the downstream switching elements is a resistance value that allows the flow of a current of a value satisfying the current at which the squib fires.
