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: RFB = 270 .
18.
Status Flag output is an open drain output requiring a pullup 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 pullup voltage < 7.0 V.
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 8.0 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.
