Table 3. Static Electrical Characteristics
Characteristics noted under conditions 4.75 V < V_DD < 5.25 V, -40°C < T_A < 125°C, GND = 0 V unless otherwise noted. Typical
values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless otherwise noted.

Notes
6. 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.
7. The logic will reset at some level below the specified Limited Operational minimum.
8. Outputs will disable and must be re-enabled via the PECCR command.
9. Outputs remain active; however, the reduction in drive voltage may result in a loss of position control.
