The L6228Q 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 VFQFPN-32 5x5 package, the L6228Q features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
