Description  
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 <7.5µsec  
(@20kHz). Also a fast over current signal is provided for IGBT  
protection.
