LV8714TA 是一款极高能效双步进电机驱动器,运行电压范围为 4 V 至 16.5 V。该器件具有极低导通电阻型 FET、无损耗电流感应、同步整流和超低待机电流 (<1µA),提供了最佳能效的系统方案。集成的稳压器可实现单芯片、单电源系统方案。内置的过电流、高温关断和低电压关断等系统保护功能可实现高度可靠的系统方案,且系统方案占位最小。LV8714TA 适用的多种应用包括保安摄像头系统、销售点 (PoS) 终端、文档扫描仪和多功能打印机。
特性   优势
     
  • Quad H-bridges with PWM based constant-current control
 
  • One-chip solution that drives dual stepper or quad DC motors
  • Power FETs with low on resistance (Upper: 0.6Ω, Lower: 0.3Ω, Total of upper and lower: 0.9Ω @ Ta=25°C, Io=1.5A)
 
  • Minimizes power loss while in operation
  • Internal current sense mechanism without external power resistors
 
  • Loss-less current sensing that enhances energy efficiency
  • On-chip regulators for logic circuits and power FETs biasing
 
  • Single supply operation without external component
  • Power saving mode with ultra-low standby current (< 1µA) when idle
 
  • Enhances energy efficiency of the system solution
  • Built-in system protection functions such as thermal shutdown, low-voltage shutdown and over-current protection
 
  • Reliable system solution under harsh operating conditions
  • Full, Half, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256 and over microstep drive is realizable by controlling VREF voltage
 
  • High convenience by abundant excitation mode, and low vibration by high resolution
