* Hi-Z : all output transistors are off. Please note that this is the state of the connected diodes,
which differs from that of the mechanical relay.
X : Don’t care
a) Stand-by mode
Stand-by operates independently with the VREF pin voltage. In stand-by mode, all internal circuits are turned off,
including the output power transistors. Motor output goes to high impedance. When the system is switched to
stand-by mode while the motor is running, the system enters an idling state because of the body diodes. However,
when the system switches to stand-by from any other mode (except the brake mode), the control logic remains in the
high state for at least 50μs before shutting down all circuits.
b) Forward mode
This operating mode is defined as the forward rotation of the motor when the OUT1 pin is high and OUT2 pin is low.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT1 to OUT2. To operate
in this mode, connect the VREF pin to the VCC pin.
c) Reverse mode
This operating mode is defined as the reverse rotation of the motor when the OUT1 pin is low and OUT2 pin is high.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT2 to OUT1. To operate
in this mode, connect the VREF pin to the VCC pin.
d) Brake mode
This operating mode is used to quickly stop the motor (short circuit brake). It differs from the stand-by mode because
the internal control circuit is operating in the brake mode. Please switch to stand-by mode (rather than the brake
mode) to save power and reduce consumption.
