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, IO = 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
