Abstract
A conducted electrical weapon (“CEW”) comprises one or more switch devices and a charge storage circuit for delivering a stimulus signal via a deployed electrode. A charge may be stored in the charge storage circuit. A first switch device of the one or more switch devices may be selectively turned on according to the charge of the charge storage circuit. The stimulus signal may be delivered via a current flow path comprising the first switch device and the deployed electrode according to the charge of the charge storage circuit.

- a terminal coupled to a first electrode of the at least two electrodes;
- and
- a second switch device coupled between the first node and the terminal coupled to the first electrode of the at least two electrodes;
- and
- a second driver circuit connected to the current source circuit at the first node and comprising:
- a terminal coupled to a second electrode of the at least two electrodes;
- and
- a third switch device coupled between the first node and the terminal coupled to the second electrode of the at least two electrodes;
- and
- a processing circuit configured to control each of the current source circuit, the first driver circuit, and the second driver circuit to selectively provide a stimulus signal based on the stimulus supply voltage to either the first electrode via the first driver circuit or the second electrode via the second driver circuit.
