Ordering number : EN7229B LB11920 Monolithic Digital IC For OA Products Three-Phase Brushless Motor Driver http://onsemi.
com Overview The LB11920 is a direct PWM drive motor driver IC for 3-phase power brushless motors.
The PWM duty can be controlled by IC inputs, and it can be used over the wide supply voltage range of 9.
5 to 30V.
Features • Three-phase bipolar drive (35V, 3.
5V) • Direct PWM drive • Built-in high and low side kickback absorbing diodes • Braking function (short-circuit braking) • Built-in forward/reverse direction switching circuit • Full complement of built-in protection circuits, including current limiter, low-voltage protection, motor lock (physical constraint) protection, and thermal protection circuits • The PWM duty can be controlled by IC inputs Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage 1 Supply voltage 2 Output voltage Output current Allowable power dissipation Operating temperature Storage temperature Symbol VM max VCC max VOUT max IO max Pd max1 Pd max2 Topr Tstg Conditions OUT1 to OUT3 T ≤ 500ms Independent IC With an infinitely large heat sink.
