Monolithic Digital IC
LB1948M
Low saturation voltage drive
forward/reverse 12 V motor driver
Overview
The LB1948M is a two-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 two-phase
bipolar stepping motor with 1-2 phase excitation mode drive.
Applications
12V low saturation voltage forward/reverse motor drive
Features
• Supports 12V power supply systems
• Low saturation voltage: VO (sat)=0.5V (typical) at IO=400mA
• Zero current drawn in standby mode
• Braking function
• Supports parallel connection: IOmax=1.6A, VO (sat)=0.6V (typical) at IO= 800mA
• Built-in spark killer diode
• Thermal shutdown circuit
• Miniature package: MFP-10S (6.5 × 5.1mm)
