LB11681H

Ordering number : ENA0665 www.DataSheet4U.com LB11681H Overview Monolithic Digital IC PWM Three-phase Brushless Motor Driver The LB11681H is a three-phase brushless fan motor driver IC. This IC uses a PWM soft switching drive-method (for low-noise drive). Since this IC includes a motor constraint protection circuit necessary for a fan motor system, highly reliable products including this IC can be designed. Also, this IC can be operated with 12V single power supply. Functions Direct PWM drive Three-phase full-wave driving method Soft switching driving Built-in lock (constraint) protection circuit Built-in lock (constraint) detection circuit FG output (provides one Hall effect sensor equivalent FG outputs) Built-in Forward / Reverse switching circuit Built-in thermal shut down circuit Built-in current limitation circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply Voltage Output current Allowable Power dissipation 1 Allowable Power dissipation 2 Operating temperature Storage temperature Symbol VM max IO max Pd max1 Pd max2 Topr Tstg Independence IC Mounted on a circuit board* Conditions Ratings 15.0 1.3 0.8 2.0 -20 to 85 -55 to 150 Unit V A W W °C °C * Mounted on a specified board: 114.3mm×76.1mm×1.6mm, glass epoxy.
