LV8731V

www.DataSheet.co.kr Ordering number : ENA1482A LV8731V Overview Bi-CMOS LSI PWM Constant-Current Control Stepping Motor Driver The LV8731V 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 : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A) Excitation mode can be set to 2-phase, 1-2 phase, W1-2 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 No control power supply required Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output peak current Output current Logic input voltage MONI/EMO input voltage Symbol VM max IO peak IO max VIN Vmoni/Vemo tw ≤ 10ms, duty 20% Conditions Ratings 36 2.5 2 -0.3 to +6 -0.3 to +6 Unit V A A V V Continued on next page.
