LB1895,1895D — Example of using a comparator to detect the direction of rotation
When the phasing is as shown above, the direction of rotation is determined to be
‘‘forward’’ if W
COMPO
is low at the rising edge of V
COMPO
, and
‘‘reverse’’ if W
COMPO
is high at the rising edge of V
COMPO
.
1)
Reverse full braking method
Braking is applied with VC = L until reverse rotation is detected. The moment that reverse rotation is detected, the driving
power is turned off or a short pulse is input.
2)
Intermittent braking method
If braking is applied according to the value obtained by OR logic in V
COMPO
and W
COMPO
together, for example, reverse braking
is applied according to the following timing.
As a result, when the rotation speed is fast, braking is applied many times; at slower speeds, braking is applied fewer times.
Furthermore, if the V
COMPO
and W
COMPO
logic combination is changed, the duty of VC = 0 V – 2.5 V also changes.
