2-channel reversible-motor driver
BA6193
The BA6193 is a 2-channel motor driver for CD player changers and electric volume switches, and other applications
as well. Because it uses a negative power supply, this IC uses the power supply of application products efficiently.
FApplications
CD players and CD-ROM drives with loading features, etc.
FFeatures
1) Reversible-motor driver with dual independent chan-
nels.
