Abstract
A pyro igniter circuit and a method for testing the same is provided. The pyro igniter circuit includes a supervisory circuit configured to: transmit a test signal having a pulse duration time below an igniter activation pulse time of a pyro igniter disconnect element and/or an ignition control signal, in response to the transmitted test signal, has an amplitude below an igniter activation amplitude of the pyro igniter disconnect element; and receive a diagnostic response signal in response to the transmitted test signal.
