1 / 7 page 91907 MS PC B8-8741 No. A0954-1/7 http://onsemi.com Semiconductor Components Industries, LLC, 2013 May, 2013 LB11683H Overview The LB11683H is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensorless control system without the use of a Hall effect device. For quieter operation, the LB11683H features a current soft switching circuit and is optimal for driving the cooling fan motors used in refrigerators, etc. Functions • Current linear drive • Built-in current limiter circuit • Output stage oversaturation prevention circuit • Coil counter-electromotive FG output • Built-in thermal shutdown circuit • Beat lock prevention circuit • Lock protection circuit • Lock detection output Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Supply voltage VCC max 14.5 V Output applied voltage VO max 14.5 V Input applied voltage VI max -0.3 to VCC+0.3 V Output current IO max 1.5 A Pd max1 Independent IC 0.8 W Allowable power dissipation Pd max2 Mounted on a board * 1.85 W Operating temperature Topr -30 to +85 °C Storage temperature Tstg -55 to +150 °C * Specified board: 114.3mm ×76.1mm ×1.6mm, glass epoxy board. Monolithic Digital IC Three-Phase Sensorless Motor Driver Ordering number : ENA0954 Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. |
