The L6208Q device is a DMOS fully integrated stepper motor driver with non-dissipative overcurrent protection, realized in BCDmultipower 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 a VFQFPN48 7 x 7 mm package, the L6208Q features a non-dissipative overcurrent protection on the high-side Power MOSFETs and thermal shutdown.
