THERMAL
Thermal Shutdown = 0 indicates that the chip temperature has exceeded 160
°
C.
The bit will reset (=1) when the temperature falls below 130
°
C. When Thermal
Shutdown =0, the spindle logic will tristate both high and low side drivers,
protecting the output circuitry.
Thermal Shutdown Warning =0 indicates that the chip temperature is
approximately 25
°
C before the device goes in thermal shut down.
0 = A sequential Spindle BEMF has not been detected
1 = Rapid deceleration of the Spindle motor or High frequency on FCOM signal.
Mask Time toggled to ”0” indicates that the Spindle BEMF is masked.
0 = Indicates error Spindle speed > 16msec/sample, either electrical or
mechanical.
0 indicate that the Spindle is in the Internal Start-Up Align Phase.
0 indicate that the Spindle is in the Internal Start-Up Go Phase.
