ROHM BA6813F, BA6811F Datasheet

Motor driver ICs

Fan motor driver IC

BA6811F / BA6813F

The BA6811F and BA6813F are 2-phase, half-wave motor drivers suited for 12V fan motors. Built-in lock detection and
automatic restart mechanisms protect motors. Compact SOP8 (BA6811F/BA6813F) packages reduce the number of
external components required.
