6 / 20 page 33997 MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA 6 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.

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. Freescale Semiconductor, Inc. For More Information On This Product, Go to: www.freescale.com |
