Features and Applications

The L6228DTR is a DMOS Fully Integrated Stepper Motor Driver with non-dissipative Overcurrent Protection, realized in MultiPower-BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device includes 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.
