Motor driver ICs 2-channel reversible motor driver BA6238A / BA6238AN / BA6239A / BA6239AN The BA6238A, BA6238AN, BA6239A, and BA6239AN are monolithic ICs incorporating two reversible-motor drivers that are suitable for driving small DC brush motors. The logic input section for controlling each motor can be easily connected with CMOSs and other control logic outputs. The torque during loading can be varied by controlling the voltage supplied to the motor with pin 8 of the output section. With a limited number of external parts, each driver has a function of two reversible-motor drivers. FApplications VCRs and audio tape recorders FFeatures 1) Two reversible-motor driver circuits are built in. (not operable at the same time) 2) Limited number of external parts. 3) Interface with CMOS devic [ ... ]
