The L6208 is a DMOS Fully Integrated Stepper Motor Driver with non-dissipative Overcurrent Protection. It is 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. The L6208 operates from 8 to 52V, with an output peak current of 5.6A (2.8A RMS) and an RDS(ON) of 0.3Ω at Tj = 25°C. It also features an operating frequency of up to 100kHz, fast/slow decay mode selection, fast decay quasi-synchronous rectification, decoding logic for stepper motor full and half step drive, cross conduction protection, thermal shutdown, under voltage lockout, and integrated fast free wheeling diodes. The L6208 is commonly used for bipolar stepper motors.
