... Reversible motor driver BA6283N / BA6955N The BA6283N and BA6955N are reversible-motor drivers with a maximum output current of 1.0A. Two logic inputs allow four output modes: forward, reverse, stop (standby), and brake. The built-in power save circuit suppresses current consumption in the motor stop mode. ...
