MST Method for enhancing transmission efficiency of MST driver and driver device for the same

摘要

When a current flowing through an MST coil is greater than a predetermined value, a full bridge circuit driving the MST coil does not provide a current. So, a method for limiting a current flowing through the MST coil regardless of the magnitude of a voltage supplied to the full bridge circuit is published. A coil current driving chip includes a detecting part, a comparing part, and a control part.
