LV8736V

Ordering number : ENA1785C LV8736V Monolithic Linear IC PWM Constant-Current Control Stepper Motor Driver http://onsemi.com Overview The LV8736V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports 1/8 step 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 stepper motors used in office equipment and amusement applications. Function Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated. BiCDMOS process IC Low on resistance (upper side : 0.75Ω ; lower side : 0.5Ω ; total of upper and lower : 1.25Ω ; Ta = 25°C, IO = 1A) Excitation mode can be set to Full step, Half step, Quarter step , or 1/8 step 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 Built-in thermal shutdown circuit No control power supply required Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Supply voltage VM max VM , VM1 , VM2 36 V Output peak current Output current Logic input voltage IO peak IO max VIN max tw ≤ 10ms , duty 20% Per 1ch Per 1ch ST , DM , STEP/DC22 , FR/DC21 , MD2/DC12 , ATT1 , ATT2 , E...
