Description  
IR2177/IR2277 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 both as a  
PWM signal (PO) and analog voltage (OUT). The analog voltage is  
proportional to the measured current and is ratio metric with respect  
to an externally provided voltage reference. The max throughput is  
40 ksample/sec suitable for up to 20 kHz asymmetrical PWM  
modulation and max delay is <7.5 µsec (@20kHz). Also a fast over  
current signal is provided for IGBT protection.
