Operating Waveform When Driven by Square Wave (CW/CCW = Low, OS = High)
To stabilize the bootstrap voltage, the lower outputs (X, Y, and Z) are always turned on at the carrier cycle
even during off time. At that time, the upper outputs (U, V, and W) are assigned dead time and turned off
at the timing when the lower outputs are turned on. (Td varies with input Ve.)
Carrier cycle
= fosc/252 (Hz)
Dead time: Td = 16/fosc (s) (when Ve = 4.6 V or more)
TONL = carrier cycle × 8% (s) (uniform regardless of Ve input)
When the motor is driven by a square wave, acceleration or deceleration is determined by voltage Ve. The
motor accelerates or decelerates according to the On duty of TONU. (See the diagram for output On duty on
page 11.)
Note: The motor is driven by a square wave if REV = High, i.e., if the Hall signals at start-up are 5 Hz (fosc = 4 MHz)
or lower and the motor is rotating in the reverse direction to that of the TB6551FG/FAG setting.
