Note 1:
Device may be supplied from IN1–IN4 or V
CC
.
Note 2:
100% production tested at T
A
= +25°C and T
A
= +85°C. Specifications at T
A
= -40°C are guaranteed by design.
Note 3:
The internal supply voltage, measured at V
CC
, equals the maximum of IN1–IN4.
Note 4:
External capacitor is charged by I
S_T
when V
S_T-DIS
< V
S_T
< V
S_T-ADJ
.
Note 5:
External capacitor is discharged by I
S_T-DIS
down to V
S_T-DIS
after V
S_T
reaches V
S_T-ADJ
.
