产品信息

The LV8740V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports Quarter-step excitation, and two channels of a brushed DC 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.

On resistance (upper side : 0.3Ω ; lower side : 0.2Ω ; total of upper and lower : 0.5Ω ; Ta = 25°C, IO = 2.5A)
Excitation mode can be set to Full-step, Half-step full torque, Half-step , or Quarter-step
Motor holding current selectable in four steps
Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
Built-in thermal shutdown circuit
No control power supply required
Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated.
BiCDMOS process IC
Excitation step proceeds only by step signal input
Unusual condition warning output pins
Forward/Reverse/Brake/Stand-by Function
