Overview
The LV8548MC is a 2-channel low saturation voltage forward/reverse motor driver IC produced by onsemi. This IC is designed for optimal performance in 12V system products and is capable of driving either two DC motors, one DC motor using parallel connection, or a stepper motor in Full-step and Half-step modes.
It features DMOS output transistors with a total RON of 1Ω (typical), operating within a supply voltage range of 4V to 16V. The compact SOIC10 package and pin compatibility with the LB1948MC make it a versatile choice for various applications.
