Overview
The LV8548MC is a 2-channel low saturation voltage forward/reverse motor driver IC produced by onsemi. It is designed for optimal performance in 12V system products and can drive either two DC motors, one DC motor using parallel connection, or a stepper motor in Full-step and Half-step modes. The IC features DMOS output transistors, a compact SOIC10 package, and is pin-compatible with the LB1948MC. It operates with a single power supply and has a built-in brake function, making it suitable for various applications.
