Notes

14.

Current measured at VSUP pin.

15.

Oscillator not running means none of the following functions are active: Forced Wake-Up and Cyclic Sense and Software Watchdog in

Stop mode.

16.

Guaranteed by design; it is not production tested.

17.

IDD is the total regulator output current. V1 specification with external capacitor. Stability requirement: Capacitance > 47 µF, ESR < 1.3 Ω

(tantalum capacitor). In Reset, Normal Request, Normal and Standby modes. Measures with capacitance = 47

µF tantalum.

Table 5. Static Electrical Characteristics (continued)

Characteristics noted under conditions 4.75 V

≤ V2 ≤ 5.25 V, 5.5 V ≤ VSUP ≤ 18 V, and -40°C ≤ TA ≤ 125°C. Typical values

noted reflect the approximate parameter mean at TA = 25°C under nominal conditions unless otherwise noted.
