LB1823M General Description


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.
