BA6955N Datasheet | ROHM

Motor driver ICs Reversible motor driver BA6283N / BA6284N / BA6955N The BA6283N, BA6284N, and BA6955N are reversible-motor drivers with a maximum output current of 1.0 A. 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. FApplications VCRs, audio devices FFeatures 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. FAbsolute maximum ratings (Ta = 25_C) 3) Interfaces with TTL devices. 4) Built-in thermal shutdown circuit.

If the IC is damaged, the short mode and open modes cannot be specified, so if the IC is to be used in applications where parameters may exceed the absolute maximum ratings, then be sure to incorporate fuses, or other physical safety measures. (2) GND potential The potential for pin 1 must be kept lower than the potentials of the other pins regardless of the...
