LV8702V 是一款 2 沟道全桥式驱动器集成电路,可以驱动步进电机驱动器,能够实现微步驱动,支持四分之一步进。电流根据电机负载和转速以半步、半步全扭矩和四分之一步进励磁进行控制,因此实现了高能效驱动。同时也降低了功耗、产热、振动和噪声。
特性
 
  • Built-in 1ch PWM current control stepper motor driver (bipolar type)
  • Ron (High-side Ron: 0.3Ω, Low-side Ron: 0.25Ω, total: 0.55Ω, Ta = 25°C, IO = 2.5A)
  • Micro-step mode is configurable as follows: full step/half step full-torque/half step/quarter step
  • Excitation step moves forward only with step signal input
  • Built-in output short protection circuit (latch method)
  • Control power supply is unnecessary
  • Built-in high-efficient drive function (supports half step full-torque/half step/quarter step excitation mode)
  • Built-in step-out detection function (Step-out detection may not be accurate during high speed rotation)
  • IO max=2.5A
  • Built-in thermal shut down circuit
  • BiCDMOS process IC
