The LB1823M 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 LB1823M output supports direct PWM drive and thus allows the implementation of low-loss drive circuits. Additionally, the LB1823M includes several associated circuits, such as a speed control circuit, and FG amplifier, and an integrating amplifier, on chip.
