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. Current Limiter Setting
Current limiter set voltage
0.4
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.
