Product overview
Description
The L6229 is a DMOS fully integrated 3-phase motor driver with overcurrent protection.
Realized in BCD 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 3-phase BLDC motor including: a 3-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 Power SO36 and SO24 (20 + 2 + 2) packages, the L6229 features a non-dissipative overcurrent protection on the high-side power MOSFET and thermal shutdown.
