Bidirectional Isolated High-Side Current Sense with 270V Common-Mode Rejection. The Circuit monitors bidirectional current from sources with dc voltages of up to 270 V with less than 1% linearity error. The load current passes through a shunt resistor, which is external to the circuit. The shunt resistor value is chosen so that the shunt voltage is approximately 100 mV at maximum load current
