Notes
17
By changing the R_DIAG resistor value, the resistance thresholds can be varied by a linear relationship.The R_DIAG resistance could
be changed by ±10% to shift the thresholds by ±10%. Design goal for resistance threshold change is ±15%. R_DIAG threshold limit may
have to be changed to accommodate ±15% change. Example: Shifting the R_DIAG resistance value ±10%, the resistance threshold
will change by ±10%. Refer to Table 5.
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions 4.75 V VDD 5.25 V; 7.0 V VVFIRE_XX 35 V; VVDIAG_X = VVFIRE_XX;
FEN 1 = FEN 2 = VDD; RR_LIMIT_X = 10 k ±1%, RR_DIAG = 10 k ±1%, -40 C TA +85 C, GND = 0, unless otherwise noted.
Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
