14. Limiting the Output Pulse Width
15. Rotation Pulse Output Pin
16. Internal Protection by V
The pulse width of the drive output signal must be less than 0.4 µs so that the external output driver would
not be damaged.
Generates a rotation pulse based on the induced voltage. The pulse can be selected by the FGC input
between 1 pulse/electrical rotation and 3 pulses/electrical rotation. 1 pulse per electrical rotation signal is
generated based on U-phase induced voltage.
Note: When FGC = Middle, the operation mode is switched to Test mode (square-wave drive)
When turning the power on/off using a low-voltage power supply, all the drive outputs are set Low to
prevent the power device from short-circuiting.
Power supply voltage 4.5 V (typ.)
Commutation signal
Internal protection by V
When the motor power supply VM is high, all the drive outputs are set Low to prevent the power device
from short-circuiting. Applying a 2.2-V input voltage to the VCOM pin sets the drive outputs (UH, UL, VH,
VL, WH and WL) Low. When the VCOM input voltage falls below 1.85 V, the output operation is restarted.
