Overview The LB1823 is a predriver IC developed for driving power brushless motors in office automation applications. A.

Choose a value such that the voltage fluctuations due to the motor drive currents are stabilized. Attach as close as possible to pins 17 and 24. Use a resistor of 30 kΩ or larger for R1. See the figure on page 6. C9, C10, R7, R8 R10 R11, R12 R13, R1.
