STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics
Characteristics noted under conditions 5.5 V ≤ V_SUP ≤ 18 V, -40°C ≤ T_A ≤ 125°C for the 33912 and -40°C ≤ T_A ≤ 85°C for the
34912, unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions, unless otherwise noted.

Notes
14. Device is fully functional. All features are operating.
15. Total current (I_VS1 + I_VS2) measured at GND pins excluding all loads, cyclic sense disabled.
16. Total I_DD current (including loads) below 100 µA.
17. Stop and Sleep Modes current will increase if V_SUP exceeds13.5 V.
18. This parameter is guaranteed after 90 ms.
19. This parameter is guaranteed by process monitoring but not production tested.
20. The Flag is set during power up sequence. To clear the flag, a SPI read must be performed.
