Notes

14.

Output-ON resistance as measured from output to V+ and ground.

15.

Product with date codes of December 2002, week 51, will exhibit the values indicated in this table. Product with earlier date codes may

exhibit a minimum of 6.0 A and a maximum of 8.5 A.

16.

Outputs switched OFF with D1 or D2.

17.

Parameter is guaranteed by design but not production tested.

18.

Fault Status output is an open drain output requiring a pull-up resistor to 5.0 V.

19.

Fault Status Leakage Current is measured with Fault Status High and not set.

20.

Fault Status Set Voltage is measured with Fault Status Low and set with IFS = 300 µA.
