BA6283N ROHM

BA6283N / BA6955N Motor driver ICs 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. Applications VCRs, audio devices Features 1) Logic and driver sections have separate ground pins this allows the IC to drive speed-variable, reversible motors by connecting an electronic governor circuit. 2) Built-in power saving circuit suppresses current consumption in stop (standby) mode. 3) Interfaces with TTL devices. 4) Built-in thermal shutdown circuit.
