Datasheet
DC Brush Motor Drivers (7V max.)
BD621xxx 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 3.0V to 5.5V, 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 deprecated
motor driver ICs. These highly efficient H-bridge driver
ICs facilitate low-power consumption design.
●Features
Built-in, selectable one channel or two channels
configuration
VREF voltage setting pin enables PWM duty control
Cross-conduction prevention circuit
Four protection circuits provided: OCP, OVP, TSD
and UVLO
●Applications
VTR; CD/DVD players; audio-visual equipment; optical
disc drives; PC peripherals; OA equipments

e) f) PWM control mode A
The rotational speed of the motor can be controlled by the duty cycle of the PWM signal fed to the FIN pin or the
RIN pin. In this mode, the high side output is fixed and the low side output is switching, corresponding to the input
signal. The state of the output toggles between "L" and "Hi-Z".
The frequency of the input PWM signal can be between 20kHz and 100kHz. The circuit may not operate properly for
PWM frequencies below 20kHz and above 100kHz. Note that control may not be attained by switching on duty at
frequencies lower than 20kHz, since the operation functions via the stand-by mode. To operate in this mode,
connect the VREF pin to the VCC pin. In addition, establish a current path for the recovery current from the motor,
by connecting a bypass capacitor (10µF or higher is recommended) between VCC and ground.
