For brush motors
Reversible motor drivers
(for two motors series)
BA6246, BA6246N, BA6247FP-Y, BA6239A, BA6238A, BA6238AN
 Overview
The reversible motor driver for output 1.0A or more for two motors drives a brush motor and incorporates one and a half
circuits of reversible motor driver. In addition, since the output section can control voltage applied to motors by output high
voltage setting pin, the torque at the time of driving motors can be varied.
 Features
1) Built-in one and a half circuits of a reversible motor driver
2) Minimal external components
3) Output voltage can be optionally set by reference voltage setting pin
4) Built-in thermal shutdown circuit
 Applications
Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
 Absolute maximum ratings (Ta=25°C, All voltages are with respect to ground)

    ... When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO. 9) Built-in thermal shutdown (TSD) circuit The TSD circuit is designed only to shut the IC off - when BA6239A, BA6238A/AN, driver outputs low - to prevent thermal runaway not designed to protect the IC or guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is activated, and do not operate the environment where activation of the circuit is assumed ...
