Abstract
An inductive load is managed to reduce unnecessary induced electromagnetic radiation as caused by unwanted voltage and/or current fluctuations. The management is accomplished through combined current and voltage slew rate limiting of a transistor driving the inductive load. This management may be effected through a combination of analog and digital circuitry.
