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  
• Low saturation voltage: V (sat) = 0.5V (typical) at I = 400mA  
O

• Zero current drawn in standby mode  
• Braking function  
• Supports parallel connection: I max = 1.6A, V (sat) = 0.6V (typical) at I = 800mA
