62012 SY 20120329-S00002 No.A2075-1/4 http://onsemi.com Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Oper ating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Semiconductor Components Industries, LLC, 2013 May, 2013 LB11669MC Overview The LB11669MC is a two-phase uni-polar brushless motor driver for fan motor. Functions

  • Two-phase half-wave drive. • Lock protection and automatic return function incorporated.
  • RD (lock detection) outputs incorporated. • Output protection zener diode incorporated.
  • FG (rotation detection) outputs incorporated. • Hall input amplifier incorporated.
  • Thermal shutdown circuit incorporated. Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum inflow current I IN max 100 mA IOUT ave 400 mA Output current IOUT peak Only when starting and lock protection is activated 800 mA Output withstand voltage V OUT max Internal V FG/RD output current I FG/RD max 10 mA FG/RD output withstand voltage V FG/RD max 30 V Allowable power dissipation Pd max Mounted on a board * 750 mW 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. 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.

  • Take care not to cause interference due to wiring of IN- and OUT1.
  • Wiring need to be short to prevent carrying of the noise. If the noise is carried, insert a capacitor between IN+ and IN-.
  • In application of connecting the CT pin to GND, lock protection and restart function are not effective.
