1 / 7 page 71812 SY/61610 SY 20100604-S00001 No.A1772-1/7 http://onsemi.com LB11685AV Overview The LB11685AV is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensor less control system without the use of a Hall Effect device. For quieter operation, the LB11685AV features a current soft switching circuit and be optimal for driving the cooling fan motors used in refrigerators, etc. Functions • Three-phase full-wave linear drive (Hall sensor-less method) • Built-in current limiter circuit • Built-in three-phase output voltage control circuit • Built-in motor lock protection circuit • Motor lock protection detection output • FG output made by back EMF • Built-in thermal shut down circuit • Beat lock prevention circuit Specifications Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max 19 V Input applied voltage VIN max -0.3 to VCC +0.3 V Maximum output current IO max *1 1.2 A Allowable power dissipation Pd max Mounted on a board *2 1.05 W Operating temperature Topr -40 to 85 °C Storage temperature Tstg -55 to 150 °C Junction temperature Tj max 150 °C *1: The IO is a peak value of motor-current. *2: Specified board: 76.1mm × 114.3mm × 1.6mm, glass epoxy board. Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Monolithic Digital IC 3-phase sensor less Motor driver Ordering number : ENA1772A 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. Semiconductor Components Industries, LLC, 2013 May, 2013 |
