LB1823, Power Brushless Motor Predriver

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.

Ordering number : EN4263B Monolithic Digital IC LB1823 Power Brushless Motor Predriver IC for OA Applications Overview The LB1823 is a predriver IC developed for driving power brushless motors in office automation applications.

A motor driver circuit with the desired output power (current and voltage) can be constructed by attaching either a driver array or discrete components at the output.

The LB1823 output supports direct PWM drive and thus allows the implementation of low-loss drive circu
