Relationship between the ENABLE Input and the Phase Current and MO Outputs
Example 1: 1-2-phase excitation (M1: H, M2: L)
continue to operate in accordance with the CK signal.
proceeded with the CK signal.
Example 2: 2W1-2-phase excitation (M1: H, M2: H)
ENABLE
Setting the ENABLE signal Low disables only the output signals. On the other hand, internal logic functions
Therefore, when the ENABLE signal goes High again, the output current generation is restarted as if phases
