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.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to VSS, all currents are defined positive into any lead. The Thermal Resistance and Power
Dissipation ratings are measured under board mounted and still air conditions.
