Overview
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.
Feature
 Built-in 1ch PWM current control stepper motor driver (bipolar type)
SSOP44J (275mil)
 Ron (High-side Ron: 0.3, Low-side Ron: 0.25, total: 0.55, Ta = 25ºC, 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)
 BiCDMOS process IC
 IO max=2.5A
 Built-in thermal shut down circuit
Typical Applications
 Printer
 Scanner
 Surveillance camera (CCTV)
 Textile machine
