LV8727

www.DataSheet.co.kr Ordering number : ENA1998 LV8727 Overview Bi-CMOS LSI PWM Current Control Stepping Motor Driver The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can do eight ways of micro step resolution of Half, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20 Step, and can drive simply by the step input. Features Single-channel PWM current control stepping motor driver. Output on-resistance (upper side : 0.25Ω ; lower side : 0.15Ω ; total of upper and lower : 0.4Ω ; Ta = 25°C, IO = 4.0A) Half, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20 Step are selectable. Advance the excitation step with the only step signal input. BiCDMOS process IC. Available forward reverse control. Thermal shutdown circuit. IO max=4.0A Input pull down resistance With reset pin and enable pin.
