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
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 A to 6.0 A. Recommended terminating resistor value: R_FB = 270 Ω.
18. Status Flag output is an open drain output requiring a pullup resistor to logic V_DD.
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 I_FS = 300 µA. Maximum allowable sink current from this pin is
< | 500 µA | . Maximum allowable pullup voltage < 7.0 V.
