Abstract
The present invention relates to a current sense device for a load arranged in a diagonal of a H-bridge comprising MOS transistors (M1, M2, M3, M4) and operating in class AB, characterized in that it includes sensor, independent from the H-bridge, for measuring the current flowing in the load. A current-voltage converter converts the current measured by said sensor into a voltage proportional to said current. The voltage is applied to a sense amplifier that determines the transconductance gain of a control amplifier of the transistors of the H-bridge.
