Abstract
A driver for driving an electromechanical device having a solenoid and a mechanical switch. The driver includes an input port, a ground port, first and second output ports connectable to the electromechanical device; and two power switches. A controller operates in a first mode to charge the solenoid and close the mechanical switch, a second mode to maintain the mechanical switch closed, and a third mode to discharge the solenoid and open the mechanical switch. In the first and second modes, the low-side power switch is on and the high-side power switch is controlled to switch between an on-state and an off-state by the controller. In the on-state a path is formed between the input port and ground via the high-side and low-side power switches, and the solenoid. In the off-state a path is formed between ground and ground via a ground diode, the solenoid and the low-side power switch.
