DC Brush Motor Drivers (18V Max)
BD622xxx Series
General Description
These H-bridge drivers are full bridge drivers for brush
motor applications. Each IC can operate at a power
supply voltage range of 6V to 15V, with output currents of
up to 2A. MOS transistors in the output stage allow PWM
speed control. The integrated VREF voltage control
function allows direct replacement of discontinued motor
driver ICs. These highly efficient H-bridge driver ICs
facilitate low-power consumption design.

(Note) 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
Mode (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 state. 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
remain in the HIGH state for at least 50µs before shutting down all circuits.
Mode (b) Forward Mode
This operating mode is defined as the forward rotation of the motor when OUT1 pin is HIGH and OUT2 pin is
LOW. When the motor is connected between OUT1 and OUT2 pins, the current flows from OUT1 to OUT2. To
operate in this mode, connect the VREF pin to the VCC pin.
Mode (c) Reverse Mode
This operating mode is defined as the reverse rotation of the motor when 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.
Mode (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.
