STMicroelectronics L6229Q
The L6229Q is a DMOS fully integrated threephase motor driver with overcurrent protection. 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. Available in VFQFPN-32 5 x 5 package, the L6229Q features a non-dissipative overcurrent protection on the high side power MOSFETs and thermal shutdown.| Part No. | L6229Q |
