LB1948MC中文资料Motor Driver, Forward / Reverse, Low Saturation Voltage, 12 V数据手册ONSEMI规格书

描述 Description

The LB1948MC 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.

特性 Features

• 20 V max operating voltage
• Good safety marginfor driving 12V motors
• Zero current drawn in standby mode
• Saving energy
