PWM Constant-Current Control

Stepper Motor Driver

Overview

The LV8736V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step

drive and supports 1/8 step excitation, and two channels of a brushed motor driver, which supports forward, reverse,

brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepper motors used in office

equipment and amusement applications.

Function

• Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated.

• BiCDMOS process IC

• Low on resistance (upper side : 0.75Ω ; lower side : 0.5Ω ; total of upper and lower : 1.25Ω ; Ta = 25°C, I = 1A)

• Excitation mode can be set to Full step, Half step, Quarter step , or 1/8 step

• Excitation step proceeds only by step signal input

• Motor current selectable in four steps

• Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated

• Unusual condition warning output pins

• Built-in thermal shutdown circuit

• No control power supply required

* Specified circuit board : 90.0mm×90.0mm×1.6mm, glass epoxy 2-layer board, with backside mounting.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.

Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,

high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating

Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
