ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 5.0 V VPWR  28 V, - 40 C  TA  125C, GND = 0 V, unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted.

Specifications given for H-Bridge A apply symmetrically to H-Bridge B.

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: RFB = 270 

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

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 ISF = 300 A. Maximum allowable sink current from this pin is 

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