DESCRIPTION

The L6235 is a DMOS Fully Integrated Three-Phase

Motor Driver with Overcurrent Protection.

Realized in MultiPower-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

three-phase BLDC motor including: a three-phase

DMOS Bridge, a constant off time PWM Current Con-

troller 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 features a non-

dissipative overcurrent protection on the high side

Power MOSFETs and thermal shutdown.
