Motor driver ICs
BA6809F / BA6819AF
Circuit 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 :
(Typical value)
where
V
LDCL
is the LD-pin clamp voltage
V
LDCP
is the LD-pin comparator voltage
I
LDC
is the LD-pin charge current
I
LDD
is the LD-pin discharge current
C is the capacitance of the LD-pin external capacitor.
For C=0.47
μ
F, for example, the charge and discharge
times are 0.25s (output ON) and 1.31s (output OFF), re-
spectively.
