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.
