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.
