While there are many types of solenoids with many configurations, DRV motor driver ICs from Texas Instruments simplify solutions to drive solenoids not only by reducing size, but by integrating more control and diagnostic features. With all the integrated features and pin-to-pin packaging, one or a small subset of DRV motor drivers can be used to drive one or multiple solenoids from a single device, and leverage a single design for different solenoid loads.
