LB11699H
No. 8315 -6/9
Application Example
The values of the capacitors between power supply and ground, between output and ground, and between the Hall
sensor inputs vary depending on the motor used. In particular, the Hall sensor input capacitors may not be required for
some motors.
<Information>
Current Limiter Setting
The LB11699H current limiter set voltage is the VLMC pin
voltage, and varies as shown in the figure to the left.
When the VLMC pin voltage is 0V, the current limiter set
voltage will be 0V and no output current will flow.
