用于TDA514x系列电机控制芯片电流体调整的限流器电路

The Motor control ICs of the TDA514x family have been provided with
a current limiter circuit. This current limit, however, cannot be set
externally.
Therefore the need exists to have a current limiter circuit of which the
current limit can be set externally.
In this report two current limiter circuits will be described all suitable
to be used with the ICs of the TDA514x family.
