High Voltage Electrohydraulic

Integrating high-performance electrohydraulic suspension into 400V/800V EV architectures requires components that can safely and efficiently manage high voltages. The system must deliver maximum performance without compromisingthe safety or driving range of the electric powertrain.

Allegro's portfolio of isolated gate drivers (IGDs) and power ICs, developed for the demanding EV powertrain environment, enables the safe and efficient control of high-voltage electric pumps and actuators for next-generation active suspension systems.

To enable the highest level of active suspension performance on modern EV platforms, leveraging the high-voltage architecture for faster response and more power, without compromising the safety or efficiency of the electric vehicle.
