Note 1: Device may be supplied from IN1–IN4 or VCC.
Note 2: 100% production tested at TA = +25°C and TA = +85°C. Specifications at TA = -40°C are guaranteed by design.
Note 3: The internal supply voltage, measured at VCC, equals the maximum of IN1–IN4.
Note 4: External capacitor is charged by IS_T when VS_T-DIS < VS_T < VS_T-ADJ.
Note 5: External capacitor is discharged by IS_T-DIS down to VS_T-DIS after VS_T reaches VS_T-ADJ.
ELECTRICAL CHARACTERISTICS (continued)
(VIN1–VIN4 or VCC = 2.7V to 5.8V, WDI = GND, TH0–TH4 = MARGIN = MR = DBP, TA = -40°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C.) (Notes 1, 2)
