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 discontinued motor
driver ICs. These highly efficient H-bridge driver ICs
facilitate low-power consumption design.

(Note 4) SOP8 package. Mounted on a 70mm x 70mm x 1.6mm glass-epoxy board. Derate by 5.5mW/°C for Ta above 25°C.
(Note 5) HRP7 package. Mounted on a 70mm x 70mm x 1.6mm glass-epoxy board. Derate by 12.8mW/°C for Ta above 25°C.

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
