Truth Table
(Spindle Motor Block)
Inputs: The “H” state is when the + input of the corresponding
phase is 0.2 V or more higher than the – input.
The “L” state is when the + input of the corresponding
phase is 0.2 V or more lower than the – input.
Note: For items marked with an asterisk (
*
), the Hall comparator goes to the high level when the S/S pin is off (standby mode).
