6. Thermal Shutdown (Tsd) Function
When the junction temperature rises up to about 175
°
C, then the output drive circuit is shut down, when the junction tempera-
ture falls off to about 160
°
C, the output drive circuit will be normally operated. It has the temperature hysteresis of about 15
°
C.
7. Rotational Direction Detecting Function
- The forward and reverse rotations of the MD are detected by the circuit, as shown in the above Table.
- The rotational direction of the MD can be learned by the output waveforms of the hall sensor and/or the driver. Let the
three hall sensors be H1, H2 and H3 respectively. If the hall sensors turn on in the order, H1
→
H2
→
H3, of the reverse
rotation, the output waveforms of the hall sensors will be as shown below.
Inversely, if the hall sensors turn on in the order, H3
→
H2
→
H1, of the forward rotation, the output waveforms of the hall sen-
sors will be as shown mext page.
