This parameter is Guaranteed By Design.
Output-ON resistance as measured from output to
Outputs switched OFF via D1 or EN/D2.
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 pull-up 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
< 500 μA . Maximum allowable pull-up voltage < 7.0 V.
