Motor driver ICs Reversible motor driver BA6219B / BA6219BFP-Y The BA6219B and BA6219BFP-Y are reversible-motor drivers suitable for brush motors. Two logic inputs allow four output modes: forward, reverse, idling, and braking. The motor revolving speed can be set arbitrarily by controlling the voltage applied to the motor. FApplications VCRs and cassette tape recorders FFeatures 1) Large output current. (IO=2.2A Max.) 2) Built-in thermal shutdown circuit.
