LB1938FA 是一款 H 桥式电机驱动器,支持低电压驱动,具有低饱和输出,使用超微型薄封装。LB1938FA 提供了由两个输入信号控制的正向、反向、制动和待机模式,是笔记本电脑、数码相机、蜂窝电话和其它便携式设备的最佳直流电机驱动器。
特性
 
  • Ultraminiature Micro8 package
  • The low saturation voltage means that the voltage applied to the motor is higher and IC heat generation is reduced. This allows this IC to be used in environments with higher ambient operating temperatures. Output saturation voltage (high side + low side): VOsat = 0.15V typical (IO = 100mA)
  • The wide usable voltage range and the low standby mode current drain of 0.1 uA make this IC optimal for battery operated equipment.
  • There are no constraints on the relationship between the input signal voltage and the supply voltage. For example, this IC can be use at VCC = 3V and VIN = 5V.
  • Thermal protection circuit limits the drive current and prevents the IC from causing a fire or being destroyed if the IC chip temperature reaches or exceeds 180°C due to large currents flowing when the outputs are shorted due to, for example, motor layer shorting or other phenomena.
