Patent number: 12132434Abstract: A driver device includes a control circuit for controlling an output stage circuit for supplying an output current to a coil, and makes a movable part move with the magnetism generated by the supplied output current. The control circuit can perform holding control to hold the state of the movable part unchanged by suspending its movement. During the holding control by the control circuit, application of an external force tending to change the state of the movable part against the holding control is detected based on the state of supply of electric power to the coil by the output stage circuit, the output current, or the current flowing through the output stage circuit.Type: GrantFiled: March 18, 2021Date of Patent: October 29, 2024Assignee: Rohm Co., Ltd.Inventors: Ryota Miyagi, Hiroki Hashimoto
