• Description: 3-phase Brushless Dc Motor Driver Ic
• Manufacturer: TOSHIBA Semiconductor CORPORATION

FUNCTION
Notes)
・ Position sensing input;
・ Coil output;
・ FRS input;
“1”: Energizing +10mV or more to the positive side of each position sensing input.
“0”: Energizing −10mV or less to the negative side of each position sensing input.
In this case, DC voltage must be within the same-phase voltage range of the position sensing input.
“H”: V
“M”: ≒ V
“L”: V
“L”: Applied voltage within the specified range of V
“H”: Applied voltage within the specified range of V
“M”: Applied voltage within the specified range of V
During testing, necessary voltage must be applied to the control input (V
driven status.
