Single-chip system in super smart power technology for a servo-valve application

This paper reports about the implementation of a single-chip smart-power IC embedding an 8-bit microcontroller, analog circuits for data processing as well as a full protected power element (an H-bridge DMOS power stage capable of 60 V, 4 A) and intended to directly control a hydraulic servo-valve. Optimized for automotive applications (active suspensions, power steering, servo-braking), it can be, for its versatility, used as well in others applications like industrial, public works, etc.
