Description

The L6229Q is a DMOS fully integrated three-

phase motor driver with overcurrent protection.

Realized in BCDmultipower technology, the

device combines isolated DMOS power

transistors with CMOS and bipolar circuits on the

same chip.

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.
