This parameter is guaranteed by design.
Output-ON resistance as measured from output to VPWR and from output to GND.
Outputs switched OFF via D1 or D2.
Accuracy is better than 20% from 0.5 to 6.0 A. Recommended terminating resistor value: R FB = 270 Ω.
Status Flag output is an open drain output requiring a pull-up 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 FS = 300 μ A . Maximum allowable sink current from this pin is
< | 500 μ A | . Maximum allowable pull-up voltage < 7.0 V.
