1 / 9 page O1806 MS IM / D3096HA (OT) No.5505-1/9 LB1845 Overview The LB1845 is a PWM current control type stepping motor driver that uses a bipolar drive scheme. It is particularly suitable for driving carriage and paper feed stepping motors in printers and similar products. Features • PWM current control (fixed off time scheme) • Digital load current selection function • Sustained output voltage: 45V • Built-in thermal shutdown circuit Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Motor supply voltage VBB max 45 V Peak output current IO peak tW ≤ 20µs 1.75 A Continuous output current IO max 1.5 A Logic block supply voltage VCC 7.0 V Logic input voltage range VIN -0.3 to VCC V Emitter output voltage VE 1.0 V Pd max1 Independent IC 3.0 W Allowable power dissipation Pd max2 With an arbitrarily large heat sink 20.0 W Operating temperature Topr -20 to +85 °C Storage temperature Tstg -55 to +150 °C Ordering number : EN5505D Monolithic Digital IC PWM Current Controlling Stepping Motor Driver Any and all SANYO Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO Semiconductor representative nearest you before usingany SANYO Semiconductor products described or contained herein in such applications. SANYO Semiconductor assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor products described or contained herein. |
