LV8804V Functional Description Control Characteristics
When 0.25 gradient limit current determined resistance pin. Minimum speed This minimum speed determined MINSP voltage. 0.5A
VCTL
current flowing motor control characteristics determined adjusting resistance resistor. connecting resistor with resistance 0.25 between GND, limit current motor current control characteristics shown diagram above achieved. increasing resistance, limit current reduced; conversely, reducing resistance, limit current increased. Since max. 1.2A, resistance must such that current flowing motor does exceed this maximum value. varying voltage between current flowing output limited. control exercised within voltage range above control motor speed. When voltage less than current limiter value determined resistance reached, motor speed limited. When voltage greater than reduced motor stops.

Insert filter capacitor with capacitance ranging from 1,000pF 10,000pF (reference value) between COMIN prevent motor startup miss-operation that caused noise. However, care must taken since excessively high capacitance will give rise deterioration efficiency delays output power-on timing while motor running high speed. Furthermore, connect capacitor between COMIN close possible order avoid effects noise from other sources. This used connect lock detection capacitor. constant-current charging constant-current discharging circuits incorporated causes locking when voltage reaches 2.5V, releasing lock protection when drops 0.5V.
