Current Limiter Application Circuit for the Motor Control IC of the TDA514x-family

Current Limiter Application Circuit for the Motor Control IC of the TDA514x-family. The Motor control ICs of the TDA514x family have been provided with an on-chip current limiter circuit. The current limit value, however, can not be set externally. Therefore the need came-up for an adjustable current limiter circuit. The method of current limiting is based upon the voltage drop across a current sensing resistor in series with the motor supply
