PWM Current Control High-efficient

Stepper Motor Driver

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

SSOP44J (275mil)

 Built-in 1ch PWM current control stepper motor driver (bipolar type)

 Ron (High-side Ron: 0.3, Low-side Ron: 0.25, total: 0.55, Ta = 25ºC, I = 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

 I max=2.5A

 Built-in thermal shut down circuit

Typical Applications

 Printer

 Scanner

 Surveillance camera (CCTV)

 Textile machine
