EVAL6229QR demonstration board using the L6229Q DMOS driver for a three-phase BLDC motor control application
  • active Active

The L6229Q is a DMOS fully integrated three-phase motor driver with overcurrent protection, realized in BCD multipower technology.

The device includes all the circuitry needed to drive a three-phase BLDC motor including: a three-phase DMOS bridge, a constant off-time PWM current controller and the decoding logic for single ended hall sensors that generates the required sequence for the power stage.

The L6229Q features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
