STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 16 V ≤ B+ ≤ 34 V, 0 ° C ≤ T A ≤ 70 ° C, and 0 ° C ≤ T J ≤ 100 ° C unless otherwise noted.
Typical values noted reflect the approximate parameter means at T A = 25°C under nominal conditions unless otherwise noted.

If any of these conditions for this not is true, then RST is activated until all operating conditions are met.
The RST terminal uses an external pull-up, which may be to 5.0 V or 3.3 V.
Guaranteed by design.
Alternately, the minimum B+ fault threshold voltage must not be lower than 12 V, and the B+ fault clear voltage must not be higher than
15.25 V. The hysteresis may be greater than 2.0 V if this requirement is met.
