Motor driver ICs
2-phase half-wave motor driver
BA6809F / BA6819AF
The BA6809F and BA6819AF are motor drivers designed for 3V and 5V fan motors. Built-in output transistors reduce
the number of external components required. The ICs have an alarm output pin (BA6809F) and Hall output pin
(BA6819AF).
FApplications
Fan motors
FFeatures
1) Lock detection and rotational speed sensing mecha-
nisms are built in.
2) Alarm output pin (BA6809F) and Hall output pin
(BA6819AF).
3) Built-in thermal shutdown circuit.
4) Operation assured with a supply voltage as low as
2.7V.
5) Compact 8-pin SOP package.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)

FCircuit operation
The BA6809F and BA6819AF 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 by :
ton (Charge time)=
toff (Discharge time)=
C S (VLDCL*VLDCP)
ILDC
C S (VLDCL*VLDCP)
ILDD
BA6809F / BA6819AF
(Typical value)
where
VLDCL is the LD-pin clamp voltage
(1.90V),
VLDCP is the LD-pin comparator voltage (0.73V),
ILDC is the LD-pin charge current
(2.2µA),
ILDD is the LD-pin discharge current (0.42µA),
C is the capacitance of the LD-pin external capacitor.
For C=0.47µF, for example, the charge and discharge
times are 0.25s (output ON) and 1.31s (output OFF), re-
spectively.
