Monolithic Digital IC
12V Low Saturation Voltage Drive
LB1948M
Forward/Reverse Motor Driver
Overview
The LB1948M is a 2-channel low saturation voltage forward/reverse motor driver IC. It is optimal for motor drive in 12V
system products and can drive either two DC motors, one DC motor using parallel connection, or a 2-phase bipolar
stepping motor with 1-2 phase excitation mode drive.
Features
• Supports 12V power supply systems
