STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 8.0 V ≤ V_PWR ≤ 28 V, - 40°C ≤ T_A ≤ 125°C, GND = 0 V, unless otherwise noted. Typical
values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions, unless otherwise noted.

Notes
13. This parameter is Guaranteed By Design.
14. Output-ON resistance as measured from output to VPWR and from output to GND.
15. Outputs switched OFF via D1 or EN/D2.
16. Accuracy is better than 20% from 0.5 A to 6.0 A. Recommended terminating resistor value: R_FB = 270 Ω.
17. Status Flag output is an open drain output requiring a pull-up resistor to logic V_DD.
18. Status Flag Leakage Current is measured with Status Flag HIGH and not SET.
19. Status Flag Set Voltage measured with Status Flag LOW and SET with I_SF = 300 μA. Maximum allowable sink current from this pin is
< 500 μA . Maximum allowable pull-up voltage < 7.0 V.
