BA6811F / BA6813F
Circuit 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 by :
C (V
LDCL
(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=1
μ
F, for example, the charge (output ON) and dis-
charge (output OFF) times are 0.40s and 2.25s, respec-
tively.
The timing chart for an occasion of motor locking is
shown in Fig. 1.
