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

Notes
9. V_DDH is fully functional when the 33997 is operating at higher battery voltages, but these parameters are not tested. The test condition as are:
a) V_DDH must be between 4.9 V and 5.1 V (200 mA to 1.4 A) for V_PWR = 14 V to 18 V.
b) V_DDH must be between 4.8 V and 5.5 V (200 mA to 1.4 A) for V_PWR = 18 V to 26.5 V.
10. Part can survive, but no parameters are guaranteed.
11. Guaranteed by design but not production tested.
