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   <7.5?/SPAN>sec
(@20kHz). Also a fast over current signal is provided for IGBT
protection.
