Phase Current Sensor Ic For Ac Motor Control - International Rectifier

Phase Current Sensor Ic For Ac Motor Control - International Rectifier IR21771/IR22771 is a high voltage, high speed, single phase Current Sensor Interface for AC motor drive applications. The current is sensed by an external shunt resistor. The IC converts the Analog voltage into a time interval through a precise circuit that also performs a very good ripple rejection showing small group delay. The time interval is level shifted and given to the output. The max throughput is 40 ksample/sec suitable for up to 20 kHz asymmetrical PWM modulation and max delay is <7.5sec (@20kHz). Also a fast over current signal is provided for IGBT protection. By International Rectifier Corp.
