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.
