STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics

Characteristics noted under conditions 4.75 V < VDD < 5.25 V, -40°C < TA < 125°C, GND = 0 V unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.

Notes

Outputs and logic remain active; however, the larger coil voltage levels may be clipped. The reduction in drive voltage may result in a

loss of position control.

The logic will reset at some level below the specified Limited Operational minimum.

Outputs will disable and must be re-enabled via the PECCR command.

Outputs remain active; however, the reduction in drive voltage may result in a loss of position control.
