Notes

14. This parameter is guaranteed by design.

15. Output-ON resistance as measured from output to VPWR and from output to GND.

16. Outputs switched OFF via D1 or D2.

17. Accuracy is better than 20% from 0.5 to 6.0 A. Recommended terminating resistor value: RFB = 270 

18. Status Flag output is an open drain output requiring a pull-up resistor to logic VDD.

19. Status Flag Leakage Current is measured with Status Flag HIGH and not SET.

20. Status Flag Set Voltage measured with Status Flag LOW and SET with IFS = 300 A. Maximum allowable sink current from this pin is

< | 500 A | . Maximum allowable pull-up voltage < 7.0 V.
