Overview
The LV8735V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports 4W 1-2 phase 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 stepping motors used in office equipment and amusement applications.

FEATUREs
• Single-channel PWM current control stepping 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 2-phase, 1-2 phase, 2W1-2 phase , or 4W1-2 phase
• 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
