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
2) Built-in power saving circuit suppresses current consumption in stop (standby) mode.
3) Interfaces with TTL devices.
4) Built-in thermal shutdown circuit.
