LB1848MC 是一款 2 沟道低电压、低饱和电压型双向电机驱动集成电路,适合用作打印机、相机和其他便携式设备中的 2 相步进电机驱动器。输出电路为双极类型,上侧为 PNP 晶体管,下侧为 NPN 晶体管,它们可以实现低饱和输出和低功耗特性,采用的却是微型封装。LB1848MC 产品可直接基于来自微控制器的信号控制电机。LB1848MC 适用于使用三输入(ENA、IN1 和 IN2)的 2 相步进电机的 2 相励磁驱动。另一点是这些集成电路包括了内置的高温关断电路,因此可提前防止集成电路烧焦或灼烧,即使发生了集成电路输出短路也是如此。
特性   优势
     
  • Low saturation voltage. VO(sat) = 0.55 V typical at IO = 400 mA
 
  • Low input voltage device available
  • Standby current: zero
 
  • Low consumption
  • Thermal shutdown circuit
 
  • Thermal protection
  • Miniature package: MFP-10S (6.5 x 5.1 mm2)
 
  • Small mounting space
  • Soft off function that reduces power supply line noise when switching from drive to standby modes. (Requires the use of one external capacitor.)
 
  • Low noise available
  • No limitations on the magnitude relationship between the power supply voltage (VCC) and the input voltage (VIN)
 
  • Easy control
  • Optimal for 2 phase excitation drive for 2-phase stepping motors
   
  • Through-current prevention circuit
