Abstract
A driver circuit for driving a solenoid, and related method, are described. A power supply charges one or more capacitors to a high voltage level sufficient to over-drive the solenoid. A switch is connected to the one or more capacitors and the solenoid. When the switch is on, the switch connects the one or more capacitors to the solenoid. When the switch is off, the switch disconnects the one or more capacitors from the solenoid. Control circuitry turns the switch on, and turns the switch off in response to sensing current through the solenoid reaches a defined maximum current.
