LB1976

Ordering number : EN6088B LB1976 Monolithic Digital IC For Fan Motor 3-phase Brushless Motor Driver http://onsemi.com Overview The LB1976 is a 3-phase brushless motor driver IC suited for use in direct PWM driving of DC fan motors for air conditioners, water heaters, and other similar equipment. Since a shunt regulator circuit is built in, single power supply operation sharing the same power supply for the motor is supported. Features Withstand voltage 60V, output current 2.5A Direct PWM drive output 3 built-in output top-side diodes Built-in current limiter Built-in FG output circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output current Maximum input current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max VM max IO max IREG max Pd max1 Pd max2 Topr Tstg Conditions VREG pin Independent IC With infinite hear sink Ratings 7 60 2.5 10 3 20 -20 to +100 -55 to +150 Unit V V A mA W W °C °C Stresses exceeding Maximum Ratings may damage the device.
