... 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. ...

... Motor driver ICs FCircuit operation The BA6811F and BA6813F have motor lock detection and automatic restart circuits. The timing of lock detec- tion and automatic restart is determined by the external capacitor connected to the LD pin. The charge time of the external capacitor is given LDCL T (Charge time)= ...

... Hall inputs of the IC are particularly long, noise can be picked up and fed into the inputs. If you have this problem, insert a capacitor C2 as shown in Fig. 5. Note that the Hall inputs have no hysteresis in this IC. FExternal dimensions (Units: mm) BA6811F / BA6813F V Hall current is given by : R1)R2)RH where RH is the Hall device impedance. ...
