Run/stop control circuit
Hall amp circuit
When the driver IC is standing by, all of its circuits except the FG amp and the hall amp are turned off.
The common mode input voltage range for V
When stopping the motor using reversing brake mode
Note3: For an explanation of the Reversing Brake mode stopping sequence, refer to the explanation of the
combined use of the short and reversing brakes when stopping the motor.
H: start
L: standby
The short brake generates less heat than the reversing brake. Therefore Toshiba recommends a
