Features

* Floating channel up to 600V for IR21771 and 1200V for IR22771 Product Summary VOFFSET (max) Vin range Bootstrap supply range Floating channel quiescent current (max) Sensing latency (max) Throughput Over Current threshold (max) IR22771 IR21771 1200 V 600V ±250mV 8-20 V 2.2 mA 7.5 µsec (@2

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 ksam
