DESCRIPTION
The L6228 is a DMOS Fully Integrated Stepper Motor
Driver with non-dissipative Overcurrent Protection,
realized in MultiPower-BCD technology, which com-
bines isolated DMOS Power Transistors with CMOS
and bipolar circuits on the same chip. The device in-
cludes all the circuitry needed to drive a two-phase
bipolar stepper motor including: a dual DMOS Full
Bridge, the constant off time PWM Current Controller
that performs the chopping regulation and the Phase
Sequence Generator, that generates the stepping
sequence. Available
in PowerDIP24 (20+2+2),
PowerSO36 and SO24 (20+2+2) packages, the
L6228 features a non-dissipative overcurrent protec-
tion on the high side Power MOSFETs and thermal
shutdown.
