Description

The L6235 device 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 PowerDIP24 (20 + 2 + 2),

PowerSO36 and SO24 (20 + 2 + 2) packages, the

L6235 device features a non-dissipative

overcurrent protection on the high-side Power

MOSFETs and thermal shutdown.
