Output Operation
Control mode selection
Either constant-current or direct PWM control can be selected by the Vref input voltage as follows:
Constant-current PWM control: Vref = 0 to 3 V
Direct PWM control: Vref = 4.5 to 5.5 V
The constant-current feature is disabled in direct PWM mode.
In either mode, the motor operating mode changes between CW/CCW and short brake alternately.
To eliminate shoot-through current that flows from supply to ground due to the simultaneous conduction of
high-side and low-side transistors in the bridge output, a dead time of 300 ns (design target value) is generated
in the IC when transistors switch from on to off, or vice versa.
The shoot-through protection permits a synchronous rectification PWM operation without controlling the dead
time externally. A dead time is also provided internally when the motor operation mode switches between CW
and CCW, and between CW (CCW) and short brake, thereby eliminating the need for external dead time
insertion.
