A driver circuit is an electronic circuit that provides the necessary current and voltage to drive and control a vehicle’s various electrical components and systems, such as lights, motors, and actuators. It serves as an interface between the control electronics and the driving load. A driver circuit is responsible for converting low voltage control signals from the microcontroller into high current/voltage signals required to operate the load, protecting the control electronics from high power loads, and improving the power transfer efficiency. Driver circuits help to control the various systems and functions of a vehicle by being a crucial component of the engine control unit, transmission control unit, body control module, and other electronic control units in modern vehicles.
