1 / 11 page LB1928 No. 6198-1/11 LB1928 Package Dimensions unit: mm 3147B-DIP28H Overview The LB1928 is a 3-phase brushless motor driver well suited for drum and paper feed motors in laser printers, plain-paper copiers and other office automation equipment. Direct PWM drive allows control with low power losses. Peripheral circuitry including speed control circuit and FG amplifier is integrated, thus allows drive circuit to be constructed with a single chip. Functions and Features • Three-phase bipolar drive (30V, 3.1A) • Direct PWM drive technique • Built-in diode for absorbing output lower-side kickback • Speed discriminator and PLL speed control • Speed lock detection output • Built-in forward/reverse switching circuit • Built-in protection circuitry includes current limiter, overheat protection, motor restraint protection, etc. Any and all SANYO 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 representative nearest you before using any SANYO products described or contained herein in such applications. SANYO 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 products described or contained herein.
