Reversible Motor Drivers for Brush Motors
2.0A or More Reversible
Motor Drivers (Single Motor)
BA6219BFP-Y,BA6222
No.11008EBT03
●Description
These motor drivers are full bridge drivers for brush motor applications, supporting output currents of up to 2A. The output
modes are available in four modes, normal, reverse, stop (idling), and braking in accordance with input logic (2 inputs). The
output voltage can be optionally set by reference voltage setting pin.
●Features
1) Large output current (lOMAX=2.2A)
2) Built-in thermal shutdown circuit
3) Output voltage can be optionally set by reference voltage setting pin
4) High output voltage can be set by low voltage input because of it has 11.4dB gain (BA6222)
5) Low standby current
●Applications
Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
●Absolute maximum ratings (Ta=25℃, All voltages are with respect to ground)
