An electronic deadbolt operator for a deadbolt lockset comprises an electronic actuator that rotates a powered driver and a follower that has a lost motion connection with the powered driver, enabling the follower to rotate with the powered driver when the follower is inside its range of travel, and enabling the powered driver to rotate freely of the follower after the follower is pushed to a travel limit. The follower is mounted to a connector driver, which drives the deadbolt, to toggle between two oppositely-disposed off-center positions relative to the connector driver. In one off-center position, only clockwise rotation of the powered driver is operative to rotate the follower. In the opposite position, only counterclockwise rotation of the powered driver is operative to rotate the follower. The interaction between the powered driver, the follower, and stops causes the follower to toggle to an opposite position after hitting a stop.
