Low-Voltage Electrohydraulic

High-performance active suspension systems that virtually eliminate body roll and absorb large road imperfections require powerful, fast-acting hydraulic actuators.

Controlling these high-power 12V/48V systems demands exceptionally robust and precise electronic solutions. Allegro's portfolio of high-power gate drivers and motor controllers is designed to efficiently manage the electric pumps in electrohydraulic systems. Our current and position sensors provide the critical, real-time feedback needed for the control unit to make instantaneous adjustments.

To deliver the ultimate in vehicle dynamics and ride comfort. By enabling systems that actively counteract cornering forces and smooth out the roughest roads, our solutions provide unparalleled stability, driver confidence, and a truly premium ride experience.
