Abstract:
A device having at least one transconducting element, for controlling the current of an inductive load through a control signal, said device comprising:a current slew rate limiter operable to provide a control input to the transconducting element; a voltage slew rate limiter operable to provide the control input to the transconducting element; and a logic device in signal communication with the current slew rate limiter and the voltage slew rate limiter, the current slew rate limiter responding to the logic device to provide the control input at one of a first plurality of selectable current slew rate control levels and then changing to at least a second one of the first plurality of control levels during a current slew cycle of the transconducting element, the voltage slew rate limiter responding to the logic device to provide the control input at one of a second plurality of selectable voltage slew rate control levels and then changing to at least a second one of the second plurality of control levels during a voltage slew cycle of the transconducting element.
