This parameter is Guaranteed By Design.
Output-ON resistance as measured from output to
V
PWR and from output to GND.
Outputs switched OFF via D1 or
D2
.
Accuracy is better than 20% from 0.5 A to 6.0 A. Recommended terminating resistor value: R
FB
= 270
.
Status Flag output is an open drain output requiring a pullup resistor to logic V
DD
.
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
