DRIVER CIRCUIT AND SYSTEM

摘要

The invention provides driver circuitry (10) with an op amp (18) for receiving feedback (24) in the form of a mirrored and scaled representation (26) of the output (30). The circuitry is adapted to operate with simple communication protocols, e.g., LIN, and provides favorable EMI performance characteristics. Circuitry (32) is provided by which the op amp (18) may selectively be switched strongly on or strongly off in dynamic response to operating conditions.
