Overview
The LV8548MC-BH, produced by onsemi, is a 2-channel low saturation voltage forward/reverse motor driver IC. 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 both Full-step and Half-step modes. This IC is particularly suited for applications requiring efficient motor control with minimal power loss.
