STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics
Characteristics noted under conditions 9.0 V ≤ VPWR ≤ 16 V, -40°C ≤ TJ = TA ≤ 125°C, using the typical application circuit (see
Figure 8) unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal
conditions unless otherwise noted.

Notes
9. VDDH is fully functional when the 33998 is operating at higher battery voltages, but these parameters are not tested. The test condition
as are:
a) VDDH must be between 4.9 V and 5.1 V (200 mA to 1.4 A) for VPWR = 14 V to 18 V.
b) VDDH must be between 4.8 V and 5.5 V (200 mA to 1.4 A) for VPWR = 18 V to 26.5 V.
10. Part can survive, but no parameters are guaranteed.
11. Guaranteed by design but not production tested.
