L6228 DMos Dual Full Bridge Driver With PWM Current Controller and Decay select
The L6228 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. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6228 features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
