Abstract
Embodiments relate to safing logic and fire set systems with a dual-mode pulse gate driver device and method of use. An aspect includes a device for a circuit having a switch, the device comprising: a gate driver including a trigger input to receive a trigger signal to initiate a test of the circuit in a first mode or a pulse through the circuit to cause a pyrotechnic chain reaction in a second mode, a power supply input and an output for driving the switch in response to receiving the signal. The device includes a trickle charge capacitor coupled to the power supply input. The device includes a high impedance coupled to the capacitor and input power circuitry, the high impedance trickle charging the capacitor and preventing a high voltage through the switch from being applied to the power circuitry in the first mode for subsequent operation in the second mode.
