MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA

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

VDDH is fully functional when the 33997 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.
