Notes
1. An unstabilized supply can be used.
2. V_VMOT = V_P, all other inputs at 0 V; all outputs at V_P; I_O = 0 mA.
3. Switching levels with respect to MOT1, MOT2 and MOT3.
4. Drivers are in the high-impedance OFF-state.
5. The outputs are short-circuit protected by limiting the current and the IC temperature.
