L6228Q Overview
The L6228Q is a DMOS fully integrated stepper motor driver with non-dissipative overcurrent protection, realized in BCD multipower technology, which bines 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...
