MLX10402 is a small DC inductive motor driver with features like current limitation, low power consumption, thermal overload protection, and microcontroller compatibility.
The MLX10402 is a motor driver IC designed to drive small DC inductive loads such as motors and lamps. It offers four driving modes (forward, reverse, brake, off) selectable via two digital inputs and includes current limitation, low power consumption, and thermal overload protection.
The datasheet provides the pin‑out, typical application circuit, and full electrical specifications, including supply voltage ranges, motor current limits, and absolute maximum ratings. It also describes required off‑chip protection for the output drivers and the behavior of the temperature‑overload circuit.
