Motor driver ICs  
2-channel reversible motor driver  
BA6238A / BA6238AN / BA6239A / BA6239AN  
TheBA6238A, BA6238AN, BA6239A, andBA6239ANaremonolithicICsincorporatingtworeversible-motordriversthat  
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)  
4) Built-in power transistor for motor driving.  
5) Built-in thermal shutdown circuit. (the circuit brakes  
the output when the chip temperature is increased  
due to such an event as motor locking)  
2) Limited number of external parts.  
3) Interface with CMOS devices. (protective resistor re-  
quired when the CMOS output is higher than 5V)
