LV8746V

www.DataSheet.co.kr Ordering number : ENA1563 LV8746V Overview Bi-CMOS LSI PWM Constant-Current Control Stepping Motor Driver The LV8746V is a stepping motor driver corresponding to the W1-2 aspect excitation drive that the selection of CLK-IN input and a parallel input is possible. It is ideally suited for driving brushed DC motors and stepping motors used in office equipment and amusement applications. Features PWM current control stepping motor driver incorporated. BiCDMOS process IC Low on resistance (upper side : 0.84Ω ; lower side : 0.7Ω ; total of upper and lower : 1.54Ω ; Ta = 25°C, IO = 1A) Excitation mode can be set to 2-phase, 1-2 phase Full torque, 1-2 phase, or W1-2 phase CLK-IN input and a parallel input can be selected. 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 No control power supply required Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output peak current Output current Logic input voltage EMO input voltage Symbol VM max IO peak IO max VIN Vemo tw ≤ 10ms, duty 20% Conditions Ratings 38 1.2 1 -0.3 to +6 -0.3 to +6 Unit V A A V V Continued on next page.
