Product Overview
Product Description
The LV8702V is a 2-channel Full-bridge driver IC that can drive a stepper motor driver, which is capable of micro-step drive and supports quarter step. Current is controlled according to motor load and rotational speed at half step, half step full-torque and quarter step excitation, thereby highly efficient drive is realized. Consequently, the reduction of power consumption, heat generation, vibration and noise is achieved.
Features
 
  • 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
