.DataSheet.co.kr Ordering number : ENA0814B Bi-CMOS LSI LV8741V Overview PWM Current Control Stepping Motor Driver The LV8741V is a PWM current-control stepping motor driver IC.
LV8741V Key Features
- Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated
- BiCDMOS process IC
- On resistance (upper side : 0.5Ω ; lower side : 0.5Ω ; total of upper and lower : 1.0Ω ; Ta = 25°C, IO = 1.5A)
- Excitation mode can be set to 2-phase, 1-2 phase full torque, 1-2 phase or W1-2 phase
- Excitation step proceeds only by step signal input
- Motor holding current selectable in four steps
- IO max = 1.5A
- Output-stage push-pull structure enabling high-speed operation
- Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
- Thermal shutdown circuit and power supply monitor circuit incorporated
