Accuracy is better than 20% from 0.5 A to 6.0 A. Recommended terminating resistor value: R
Status Flag output is an open drain output requiring a pullup resistor to logic V
Status Flag Leakage Current is measured with Status Flag HIGH and not SET.
Status Flag Set Voltage measured with Status Flag LOW and SET with I
