The Toshiba PWM chopper type 4 ch H-bridge motor driver can drive two steppers, two DC brushed motors and one stepping motor, etc. by combining 4 ch H-bridges and it can also drive dual DC brushed motors or stepping motors for large-current drive by setting large mode. The VM power supply voltage can be used 6.3 V or more hence it is optimal for battery powered applications with 7.2 V power supply.
