1 / 16 page 11707 SY IM B8-5416 No.7115-1/16 LB1946 Overview The LB1946 is stepping motor drive IC that implements PWM current control bipolar drive with a fixed off time. This IC features 15-current setting levels using a fixed VREF voltage and supports for microstepping drive from 1-2 phase excitation to 4W1-2 phase excitation drive. This device is optimal for driving stepping motors such as those used for carriage drive and paper feed in printers. Applications • PWM current control stepping motor drivers Features • PWM current control with a fixed off time • Logic input serial-parallel converter (allows 1-2, W1-2, 2W1-2, and 4W1-2 phase excitation drive) • Current attenuation switching function (with slow decay, fast decay, and mixed decay modes) • Built-in upper and lower side output diodes • Simultaneous on state prevention function (through current prevention) • Noise canceller function • Thermal shutdown circuit • Shutoff on low logic system voltage circuit • Low-power mode control pin Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Motor supply voltage VBB 50 V Peak output current IO PEAK tw ≤20µs 1.75 A Maximum continuous output current IO max 1.5 A Logic system supply voltage VCC 7.0 V Logic input voltage range VIN -0.3 to VCC V Emitter output voltage VE 1.0 V Operating temperature Topr -20 to +85 °C Storage temperature Tstg -55 to +150 °C Allowable power dissipation (IC internal) Pd max Ta=25 °C, independent IC 3.0 W Ordering number : EN7115 Monolithic Digital IC PWM Current Control 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 using any 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. |
