<p>An improved current limiter for electrical circuits utilizes a current limiter, a clock, a memory and a processor. The memory contains a two dimensional table having time data in the first dimension and current data in the second dimension. When a control line is activated, the processor receives timing data from the clock in discrete timing events. For each timing event, the processor looks up a current value using the two dimensional table. The current value is then applied by the processor to a current limiter that limits the current to a circuit. The look up sequence can utilize discrete (rounded) timing values, linear interpolation, curve fit interpolation, or other interpolation techniques that can be processed by the processor. The two dimensional table can be pre-loaded from an external source or, in the alternative, the processor can calculate the discrete time values and current values and then load the two dimensional table before operation of the device. <IMAGE></p> |
