L6208PD Datasheet PDF - ST Microelectronics

The L6208PD is a DMOS fully integrated Stepper Motor Driver with non-dissipative over-current protection, realized in BCD technology, which combines isolated DMOS power transistors with CMOS and bi-polar circuits on the same chip. The device includes all the circuitry needed to drive a 2-phase bi-polar 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. This device features a non-dissipative over-current protection on the high-side power MOSFETs and thermal shutdown.
