LV8805SV
*6. SOFTST pin
This pin is used to set the soft start.
By connecting a capacitor between this pin and GND, the motor speed can be increased gradually.
When the pin voltage exceeds 2.5V, the soft start is released, and the LV8804V is switched to normal control.
If the soft start function is not going to be used, connect the pin to the VREG pin.
*7. OSC pin
This pin is used to connect the capacitor for setting the startup frequency.
A capacitor with a capacitance ranging from about 500pF to 2,200pF (recommendation) must be connected between
this pin and GND.
The OSC pin determines the motor startup frequency, so be sure to connect a capacitor to it.
<How to select the capacitance>
Select a capacitance value that will result in the shortest possible startup time for achieving the target speed and
produce minimal variations in the startup time. If the capacitance is too high, variations in the startup time will
increase; conversely, if it is too low, the motor may idle. The optimum OSC constant depends on the motor
characteristics and startup current, so be sure to recheck them when the type of motor used or circuit specifications are
changed.
*8. VG, CP, and CPC pins
These pins are used to connect the capacitors to generate the pre-drive voltage and stabilize the pre-drive power
supply.
Be sure to connect these capacitors in order to generate the drive voltage for the high-side (upper) output DMOS
transistor.
*9. VREG pins
These are the control system power supply pin and regulator output pin, which create the power supply of the control
unit. Be sure to connect a capacitor between this pin and GND in order to stabilize control system operation.
Since these pins are used to supply current for control and generate the charge pump voltage, connect a capacitor with
a capacitance that is higher than that of the capacitor connected to the charge pump.
Both the VREG pins (pins 3 and 4) must be short-circuited on the print pattern.
