ELECTRICAL CHARACTERISTICS (continued)
(V IN1 = V IN6 –V IN8 = V GND , V IN2 –V IN5 = 2.7V to 5.5V, WDI = ENABLE = GND, TH0–TH4 = MARGIN = MR = DBP, T A = -40°C to
+85°C, unless otherwise noted. Typical values are at T A = +25°C.) (Notes 1, 2)

Note 5:
100% production tested at T A = +25°C and T A = +85°C. Specifications at T A = -40°C are guaranteed by design.
Device may be supplied from any one of IN2–IN5, or V CC .
The internal supply voltage, measured at V CC , equals the maximum of IN2–IN5.
External capacitor is charged by I S_T when V S_T-DIS < V S_T < V S_T-ADJ .
External capacitor is discharged by I S_T-DIS down to V S_T-DIS after V S_T reaches V S_T-ADJ .
