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.
