L6234 Datasheet (STMicroelectronics) - Three-phase motor driver

L6234, Three-phase motor driver

The L6234 is a triple half bridge to drive a brushless DC motor.

It is realized in BCDmultipower technology which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip.

By using mixed technology it has been possible to optimize the logic circuitry and the power sta
