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 μ sec (@20kHz). Also a fast over
current signal is provided for IGBT protection.
